Has anybody installed 295 width tires on the rear of the IS yet, do they fit? Here is a calculator showing the difference for a 19" set-up:

Tire Size Comparison 19"

Specification: 255/35-19 / 295/30-19
Sidewall: 3.5in / 3.5in
Radius: 13.0in / 13.0in
Diameter: 26.0in / 26.0in
Circumference: 81.8in / 81.6in
Revs/Mile: 775 / 777
Difference: 0.0% / -0.2%

Stock:
Specification: 255/40-18
Sidewall: 4.0in
Radius: 13.0in
Diameter: 26.0in
Circumference: 81.8in
Revs/Mile: 775
Difference: 0.0%


Since some may ask what is the point? The point is that the sidewall profile of the front tires match the rears as this is most people's complaint with the stock tire set-up.

Thanks guys for any input!!

 

wellll, a 10.5" wide rim will fit in the back. probably should be more concerned about that before the tire, imo

 

wide tire doesnt mean wide rims
also wide rim doesnt mean you have to use wide tire too

 

i would love to know this as well . . . Right now Im definately wanting to go with 10" wide rim in the rear with the biggest tire i can . . . so this is some good info.

 

Not flaming but just wondering why y'all want to go so wide? 275's should be able to tackle anything the 350 can put out in stock form. Going with a wider wheel and tire will only add to the rotational inertia that will actually hurt the performance.

 

wah?!

 

he means you can do ridiculous stuff like this

 

lol S14 haha
i order my rims 19x8.5 19x9.5 with 225/35/19 235/35/19
same spec as the ings one for my IS250
i still like the stretch look for rim and tire

 

why? it gives you ZERO wheel protection and hurts performance. I'll be in the "told ya so" line when a tire bead gives out during a hard turn.

 

seriously..thats just bad advice and it should be deleted

wide tire can...not mean wide rim. you can overload your rim to a degree and be fine

however wide rim DOES men wide tire...unless you want to look like a fool and be replacing tires left and right

 

I have personal experience with this. Bought 265's for 9.5 in rear wheels. Took a turn out of the parking lot a bit too tight and put a 3 in scratch on the edge of my passenger side wheel. Needless to say, I had 275's put on yeasterday. They will protect the rim better and they look a hell of a lot better (IMHO). Anyone need some lightly used 265/30 19's?

 

super old thread, I know. But if I'm reading this right, you put 19" rims in front and slapped 275s on them and they didn't rub??

 

Just putting this here for anyone interested in fitting wider tires/wheels in the rear.

I'm on 19 x 9.5 with a +35 offset and sitting on a 285 / 30 R19 tire (Hankook Evo 2)

Rear guards are rolled. I do rub on heavy bumps otherwise its all good. I'm going to trim the rear on the contact areas. Otherwise very happy with the look and love the wide look from the rear.

 

I'm sure its been done, but you would need new wheels before you can put a tire on that wide. 295s are far to wide for the stock wheels.
