Tires: How wide can you go on stock ray wheels??

Mr_Z · 09-22-2010, 03:07 PM

Hello,
I couldn't find a clear answer in this forum...

Tires: How wide can you go on stock ray wheels without any rubbing on fenders or fitting issues with the wheels??

The suspension has not been modified and I don't want to put any spacers.

Any suggestions for tires brands/specs?

Thanks alot guys!

From what I see.. if you want to fit the same tires brand front and back:

Ventus V12:

Front Either
245/40ZR19 (26.7" vs 26.8" oem)
255/40ZR19 (27.1" vs 26.8" oem)

Rear:
305/30ZR19 (26.3" vs 26.5" oem)

Anybody knows if this setup will rub? I am not to worries about the front but what about the back?

Also the V12 305's require a rim of 10.5" to 11.5". I beleive the stock rays wheels are 10"? Any thoughts?

Cheers!

A lot of people are running 305 on the rear, and I will be included in that group post-winter.

I was running (until yesterday!) 305/30 Hankooks on the stock Rays wheel with no problems whatsoever, and I am also running spacers. Here's a pic of my stock wheels with 275/35's in front with a 15mm spacer and 305/30 in the back with a 20mm spacer. No issues at all.

I just yesterday had my new wheels put on and retained the spacers and the same Hankooks now. Here is that pic.

You will have no problems at all running a 305 in the back with the stock wheels. I now intend to lower the car about an inch and I don't anticipate any clearance issues. Alignment issues maybe, but I'm sure that they won't hit anything.

I hate to say it but the OEMs look better IMHO!

If they had some concavity, they would be straight sex. It will also look much better when lowered in my opinion.

probably not the best in terms of traction/safety, but it fits

How does widening decrease safety? and traction? Your gaining traction if anything.

You are stretching a tire beyond its recommendation, there is a reason for that. For racing, it is probably okay. Street tires? I don't know.

The car already plows like a truck stock, extra wide tire in the back and still the skinnys in front? The car will turn worse than my Prius!

If anything you will be making the tire bulge as your putting a slightly to large tire on the rim as opposed to the stretched tire that is on the rear rim now. Also you can go 275 on the front as many people have and that will retain the same 30mm difference in width between the front and rear of the non-Nismo cars. If anything your actually reducing the difference between going 245f 275r to 275f 305r, from a 11% difference front to rear going to 10% difference. Whopping difference, I know

Hi,
Small tires up front and large tires in the back do not mean that the car will turn worst then a Prius! IT depends on the car’s need... Check out the Ferrari Enzo for example:
FRONT 245/35 ZR19 – REAR 345/35 ZR19 !! And I am pretty sure it handles pretty well

But I agree with you and most of the others that you should not stretch a tire beyond its recommendation. A therefore, I do not suggest going with tires that require rims of 10.5” if you have the stock wheels. ...I won’t !

Too bad I can't find 305's that fit on 10" wheels...

Thats exactly what he is saying, the car needs larger tires in the front as it already understeers with 30mm difference between them. So by making the difference front to rear larger by going bigger in the rear and staying the same in the front your going to have more understeer.

You can go to 295's on the front without rubbung but I wouldnt go above 255 for street tires.
