Im getting four new tires and this is what my friend has. Will this work w no issues? I have the 19" Forged rims off the g35s?

Also is it normal to have a thicker tire up front??

Fronts: 225/35/19

Rears: 255/30/19


thanks in advance for any help out there..

 

dunno, how about checking the wheel and tire section

 

The 2nd number represent the percentage of the width. go here: http://www.1010tires.com/TireSizeCalculator.asp

 

i thought the second number was the thickness??????????????????

 

what size rims?

 

What's the width?

 

rims are 19" g forges and the height are 35 on the front and 30 on the rear.

 

NOOBS!

XXX/XX/XX YR

First Number is the WIDTH of tire in millimeters. I have 285 rear, 245 front.

Second number is the Aspect Ratio or heigth of the sidewall in millimeters.

Third Number is the size of rim that the tire was meant to fit on.

The letters are the speed rating of the tires, Y is the highest rating at 186+ mph.

Youre setup is fine OP. its normal for the numbers to be like that.

 

like I said. ITS A PERCENTAGE of the width.

 

wtf is percentage of the width.

anyways.
Thanks alot djmatrix. Was just a little worried about the height diff.

i guess i ll go drop another 700 into the z for the tires. Again. it hurts so good though...

 

Okay, here's some help since you are lost. I have G35 19" wheels also. You can run two combinations...

225/40/19
245/40/19

OR (like me)

235/35/19
255/35/19

The second option works, is barely off from stock, and I found the Goodyear Eagle F1's (and BF Goodrich KDW2's) cheaper in the second option.

And here are your wheels sizes for future reference.
Fronts: 19 x 8 +33(or +30) offset
Rears: 19 x 8.5 +33(or +30) offset
I forget the offset, but it is neligible.

BTW, your sizes are too small meaning the overall height is not big enough. Look here http://www.miata.net/garage/tirecalcold.html

 

those sizes in the begining is what im going to buy. You mean they will not work???

Here they are again.

Fronts 225/35/19

rears 255/30/19

 

i dunno about that. i bought some rear tires to replace my brother drag radials and they were 30 series in the rear while the fronts were 35 series. the traction control went nuts. it was cutting power into and out of turns. made the poor kid fear for his life. his set up was something like 255/35/18F and 285/30/18R

i'd stick with something that has the same series wall.

for me, i run: 255/35/19 fronts and 275/35/19 rear

 

my setup now is

front 225/40/19


Rear 245/40/19

I just really need to know if theyll fit my g35 forgeds?

the whole 5mm thinner in the back is making me wonder wtf ??????????????????????

 

i'd suggest you talk to one of the sponsors about the tires. they probably have the best info.

 

wow... I've never understood what the all those numbers meant up until now. thank you for showing me.

 

oh and I'm being tremendously sarcastic.

 

okay finally. I got you now, the light just came on. So it is cool that i run 30s on the rear with a 35 on the front . I didnt know wtf was going on earlier thanks alot for the info much appreciated

 

ok cnin... I'm sorry, I asked for rim specs... I more meant 'what is the width'. you can say (for example): 19x8.5f 19x9.5r

and if you do the math, or use a tire size calculator you can figure out what the overall diameter will be between the front and back

 

this is not a blanket statement. it depends on the staggered fitment you are using.

if you used the same size tires front and rear, with different profiles (i.e. 245/35 245/30)

you have to do the math to see if the 225/255 size is compatable! unless someone addressed the exact sizes you mentioned.
