hi im trying to match some tires. i jus ordered my volk te37 my rear width rim is 10.5 now im looking for tires. how would a 275/30/19 tire be on our cars?

 

you know you have to roll the fenders to fit 10.5 rims right?

anyway, you need more like 295 or even 305 for a 10.5" rim, I have 275 on a 9.5" rim and thats "proper size" not over sized or anything.

dont totally feel like figureing out the sidewall percentage, you had 110mm sidewall on a 18" rim, now you have a 19" rim, so subtract .5inches of sidewall from 110mm(gotta do the conversion there, I want to say ~12mm=.5" so now you need like 98mm sidewall, with a 295 tire. sits your right between 30 and 35 so who knows. 30 will be smaller diameter than stock, 35 will be larger.

 

yes i am aware of the fender rolling thanks. my car has 17" wheels its an enthusiat model. i really dont want 30 series i think that would be to thin so i will look at a 285 or 295/35 19 how do dyou think this would work

 

A 30 aspect ratio is a little low. You would have no side wall!

Your drives would go from fun to being sweaty apprehensive trips filled with worries about potholes. I been there. If you have HREs one bad pothole f**ks up a $1200 rim. ouch!

 

ok i think i decided between
falken 285/35/19 rears
and michlen pilot 295/35/19 rears

and matching 245/35/19 front on either brand i choose which would you choose?

 

I think youd be better off with a 295, mainly just cause it seems like you got such wide rims only to get 285 tires, you could get 285s onto 9.5" rims. just seems like a waste.

but the 285/35 would get you much closer to the stock diameter that you need... you could do a 305/30 too, the sidewall wouldnt be that thin because they are so wide. not like a 245/30 tire.

kinda wierd tho, there isnt a rea good tire size and sidewall ratio that will give you near stock diameter.

 

Your stock tires are 25.9" tall front, and 26.3" tall rear. Ideally, you should keep the same ratio, or at least close.

THe closest combo would be 245/35-19 front @ 25.9" and 275/35-19 at 26.6".

a 275/35 has a recommended rim width of 9-11" according to tirerack's spec on the S-03, so it being too narrow for a 10.5" rim is bs. Also as for rolling, that depends on the offset of your wheels. My 19x10 with 275/35 and +27 offset don't rub the fenders and have plenty more room.

Hmm... a couple of comments:

Says who? This depends on the offset of the wheel... our Nissan/HRE SEMA 350Z had 19x10.5 on the rear with 295/30-19 tires. NO mods were necessary.

I drove (actually, hammered ) our 350Z for several weeks on 30 series tires front & rear- Have NEVER bent a wheel. My brother runs HRE 448R 19x9 + 245/35-19 front & 19x10 + 285/30-19 rear on a heavy GS300- in 18 months he has never bent a rim. Are you saying the HRE wheels are not durable?
I have not heard this complaint- I'd be interested to know if our customers are having rim bending issues!

The good thing about HREs (or most American made three-piece wheels) is that you can replace the damaged rim component if ot is ever curbed or damaged. The Japanese three-piece wheel manufacturers will not sell replacement rim pieces. You must purchase a new wheel.


Back to the original question: A 275/30-19 is a bit stretched on a 10.5" wide wheel, but it works.
The answer to this is tricky- you must coordinate the rear tire size with the front wheel dimensions and tire size. Can you tell us a bit about how you plan to use the car and the front wheel width?

Arg, what i would give to be able to afford HRE's. They are the best looking wheels in my opinion. And with the ability to be completely custom, you can get the exact look you are looking for. Damnit man! Someone buy me some HRE's. Hehe.

Back on subject, i was thinking 295/30's would be perfect. But after reading, what would the perfect size for 19x10.5's be? On the front i noticed John350z got 245/35. Seems a little bit thin to me, but again, im probably way off.

You are mis-informed. I am runing 10.5" rims with 285/35 tires WITHOUT rubbing issues and WITHOUT rolling fenders. In fact the HRE sema car was runing 295/30 tires on a 10.5" rim AND Eibach lowering springs with a 1.2" drop WITHOUT rolling fenders.

I see this rolling fenders thing a lot lately. Where is this incorrect info coming from?

It all depends on your offsets.

I think its because John350z had to roll his fenders when he put on his TE-37's. He uses 19x10.5 with a +22mm offset. It looks pefect IMHO.

would a 245/35 tire fit my front 19x9.5?

 

Makes sense. I think my offsets are in the upper 20s like 28 or something which would push the wheel in a little more.

Jeff

 

I think the tire would be spread quite a bit on 9.5" rim.

I have a 255 on a 9" rim and the sidewall is just about flush with the edge of the rim. I know that if I put a 245 on the 9" rim the sidewall would be rolled inward slightly so on a 9.5" rim it would be even more so.

Basically you will rub the rim on a curb before you rub the sidewall with that setup.

Jeff

 

hmmm well from what I saw, if you ran a 10.5 inch rim it would stick out from the fenders a bit, which in my state, is illegal. sorry if that wasnt clear, its not impossible, but it is illegal, atleast here.

I still dont see why youd want 275 on 10.5" rims tho. even if its doable, could have saved money and weight and gotten 9.5" rims that would have the same tread width look to them and traction. if I had 10.5" rims Id damn well be sure my tread was wider than someone with 9.5" rims.

 

how would the 295/35 look in the rear on the 10.5 inch rim

 

295s would look great on a 10.5" rim but you would have to go to 295/30 to get the right diameter. 35 is to tall and would effect the speedo and VDC.

Several guys here have done 295s on the rear and it looks real tough. Search (zland) he did 295s on 18" wheels and search (HRE sema) they did 295s on 19" wheels.

Jeff

 

I don't think ALL HREs are $1200, and can be had in certain finishes, sizes and on a group buy for a few hundred less, if you really want HREs (or any wheel) don't compromise, just save up more $$, or sell more toys.

 

I was just using an example... I know HREs vary in price. I also know they are a high quality wheel. I was just using an expensive wheel to illustrate the possibility of an expensive accident at the hands of a pothole. I have had two different wheels ruined because my rubber did not have enough sidewall. and I would hate to see someone else have the same problem.
Low sidewall has Bling! factor but means less protection for your wheel!

 

I agree. I have 35s and the sidewall is awfully short. You get down to 25s or 30s and it would be almost like riding on the rim.
