I'm not excited about this ... but whatever

complained to nissan and I guess they've come up with excuses ever since they fixed the 03's .. can't trust a nissan to hold alignment is basically what the conlusion is ..


SO ..

I need to buy new front tires for my '07 Touring Z and go get a lifetime alignment from firestone so I don't have to keep buying tires twice a year

(drive 100 miles daily for work)


got a question ..

I was going to get the BF Goodrich G-Force tires off of tire rack ..

300 tread rating and AA traction .. seems ok and only $150 or so each compared to the $230 for the stock 120 tread wear and A traction


if I got the new BF Goodrich tires for the rears .. could I put the stock 245's on the fronts for now until they wear out (probably 10K miles) then put front BF's on ?

if so, should I stay with 245 on the rear or bump it up to 255 ?


oh and anyone know a tire that is similar price but lasts longer .. I'm sorta looking for good price, traction, yet lasts as long as possible .. not worried about the ride or noise (its a sports car)

plus the BF's have a bada$$ tread on them

 

Just throw 245/40'd up front and stick to stock rear size tires till you can buy wider wheels.

 

aight sounds good ..


I'll just put the stock rear tires on the front since they still have plenty of tread and get some new rear tires .. then when the fronts wear out again get new that match the rear

 

you should have just gotten proper sized fronts and left the rears alone..

now i bet you have a ugly bulge on your front tires, and your steering wheel feels slightly heavier..

 

I haven't done anything yet ..


so should I just get new ones for the fronts and leave the rears?

this is why I asked before doing it



I'm not going to do anything until tomorrow or mid week so I can check around at prices (might get a discount where I work)

 

I would not move your rear 245/45-18” to the front.

Instead I would do this:
…and, I’m not sure you understand what terrasmak is telling you.
Nooo!

I think terrasmak is telling you to get new front tires that are wider than stock so that when your rears wear out (and they should wear out long before your new fronts do) you can buy new wider wheels (maybe 8.5” front and 9.5” rear) on which you mount wider rear tires but keep your new wider front tires.

Question: Are your fronts wearing faster than your rears?

Huh?

1) Why would he “have a ugly bulge on your front tires”?

2) What would make “your steering wheel feels slightly heavier”?

--Spike

 

tire bulge = larger tire on smaller wheel = synonymous to the offroad look

heaver tire = slightly heavier steering feel

The latter I have noticed when I drove a G coupe with a 275 in the front, and I definitely noticed the heavier steering wheel. But it may or may not be felt by the other person since many people do it all the time and don't complain..

 

I'm not sure we are even talking about the same thing. The current discussion is about 245's on the front. You are the only one who mentions 275's on the front.

--Spike

 

aight im confused now ..

I'm not getting new wheels .. I like the stock ones for now



the alignment is off on my front so with 13K miles the fronts are chewed up on the inside (feathered) and need replacing along with an alignment ..


the rears are still fine with plenty of tread .. fronts have plenty of tread everywhere except the inside where it is worn ALL the way down

I was thinking of putting the stock rear tires (good) on the front rims .. then buying new rears (bf goodrich)

or should I just stick new (stock size) BF's on the front and just replace the rears with stock size when they wear out around 25K or so


.............

I don't race the car .. its my DD .. mainly interstate use and stop / go traffic .. I play with it every now and then and maybe bark the tires or slide around a corner but not often enough to be wearing the rears out quickly

now my camaro is a different story .. cant keep a set on that car longer than 3,000 miles

 

Keep complaining until Nissan gives you new tires, next get the free engines they have been giving out..

 

I tried complaining .. even made the damn lady that called from nissan consumer affairs question herself a couple times ..

"sir its a sports car with a soft compound tire"

.. "well I got plenty of tread on the rest of the tires"

"your front needs an alignment, we dont warranty adjustments" (I was 5 months out off the 12 month rule .. had 11K on the car)

"so I have to replace my tires every 10K miles ?? "


" uhhhh .. ummm .. no? "

...............................

haha .. didn't get anywhere at all except this quote that pissed me off enough to just give up

"well if you buy new front tires from the dealer they will align the front for free"



anyways ..


free engines? nothing is wrong with my HR yet after 13,000 miles .. but sounds interesting

 

didn't mean to confuse

what i was saying was that I felt a difference when I drove wider tires on the front of a car. The OP is going from 225 to 245 up front, but he probably won't even feel the difference in weight..

but why put an improper tire size on a 8in. wheel? Stick with the proper tire size don't be all ghetto

 

only reason I considered it was b/c I saw a few threads where people were putting wider tires on stock rims .. either 10 or 20 over stock

I was going to put the rears on the front and then get wider new tires for the rear .. therefore both front and back being wider than stock ..


but I'm going to stay stock sizes .. I dont have any problem with traction or anything

just got a problem with keeping the front end aligned .. but I think that is every 350z

 

You can't run the stock rears up front, they are to tall. The are 3/4 inch taller than the stock fronts.

 

im just gonna stick with stock sizes on front and back ..


the inside of each front tire is worn almost all the way down to no tread left .. rest of tire has plenty of tread


should I replace them now, or swap them over like nissan suggests (left to right) .. how much longer could I run them before buying new tires?


I went to firestone today and the lifetime alignment is $150 and they said they recommend I bring it in every two oil changes (6K I guess) or however often I want ..

the person I talked to also said that cars are NOT aligned correctly from the manufacturer .. so if that is true no wonder my tires are chewed up already


they quoted me $150 each for some potenza RE760 tires that have a tread wear rating of 340 .. so thats cheaper than tire rack (considering no shipping) and better wear rating than the BF's .. plus they will "match" my OEM rear tires beside the model #


so basically my question now is swap the fronts over and get more life out of them or buy new ones?
(I can swap the tires over at work on the tire machine for free)

 

the guy from Firestone is right, the car's alignment is not done in the factory at Japan..

The Z is sent to dealerships and they do the alignment. And sometimes, the alignment machines at the dealerships are not calibrated correctly, which result in improper alignment. That's most likely why you have inner tread wear..

 

It sounds as though your front tires are too worn to do a successful right/left swap. If “the inside of each front tire is worn almost all the way down to no tread left,” swapping right/left gives you a front tire without an outside thread. That means in aggressive turns you could lose traction.

I really think you should consider new tires on the front. You can install either 225/45-18” or 245/40-18” tires on the front. Go with 225’s if you prefer the slight under steer Nissan provides in the stock setup, or go with 245’s (245/40-18” but not moving your 245/45-18” rears to the front) on the front if you prefer neutral steering.

Since your plan is keeping the stock wheels, the widest you can go on the rears. when you replace these, is 255mm. You may decide in the end to keep the stock size (245/45-18”).

One more point: if you do go with 245/40-18” on the front and run stock 245/45-18” on the rear, you will have neutral steer which is really fun. However, your rears will wear faster than your fronts; and with this square-width setup with rears more worn than the front (and consequently less grip), you might experience over-steer. Just be cautious if you go with this setup.

how aggressive would of a turn would it have to be ..


I DD the car so it would be nice to maybe last another few thousand miles so I can round some spare cash up first
(I got $$ in the bank but don't want to blow it if I don't have to if you know what I mean .. work is somewhat slow lately and being payed on commission doesn't help)

there not completely worn down .. but its getting pretty low in some spots of the feathering ..

here is a pic I took a few thousand miles ago .. I did notice slight feathering at 6,000 miles .. I just didn't take any notice b/c never had this problem before .. wasn't until around 10K the noise started

 

You are referring to an old problem that is fixed long ago.

When Nissan became aware that the Z needed slightly different alignment and that some of its dealers had alignment devices unable to set the precise tolerance, the company required its dealers to recalibrate the alignment equipment, and provide certification.

If you are concerned that your Nissan dealer is using alignment equipment that isn’t accurate, ask to see the dealer’s latest calibration chart.
