275/40ZR18 Sumitomo HTR Z III on a +15 rim will rub in the front on stock suspension for those wondering. Oddly enough only on the driver side since it seems that the car is slightly lower on that side.

Time to order a pair of 35 series tires.

 

Doesn't suprise me, that tire is too tall for the front, much taller tire then stock.

 

Time to lose some weight . . .

 

Sounds reasonable even though you did not mention wheels size.

 

haha well the height difference is with me out the car.

Oh, the wheels are 9.5x18 +15.

Yeah, previously I asked around in other threads and searched to find the general consensus was that it would not rub.

 

oops double posted

 

Considering 255/40's on that offset and width usually rub, the 275/40 was a given.

 

why would a 275/40 not rub on a lowered Z in the front? and if its honestly because one side is slightly lower... raise it. or get camber arms and fix it that way.

and why would you run that tire on a 9.5 in the first place?

 

I didn't realize that anyone was questioning whether that tire size would rub or not.

 

I run a 275/40 on my 9.5, on the rear of course. Looks fine to me.

 

Uhh yeah, 275 is perfect for a 9.5. You wouldn't want to run much wider maybe 285 but you do not need a 10.5 or wider wheel for 275. A 10.5 is typically used for a 300+ series tire.

Some guys here like the stretch tire look so a 10.5" wide wheel with 275 tire would achieve this look. A stretch tire is not good for handling or the tire itself however. From a tire manufacturers point of view 275 on 9.5 is the proper size. Actually a 275 tire is approved for even a 9.0" rim. So there is nothing wrong with 275 on 9.5".

Just as an FYI a 9.5" rim is 10.5" wide lip to lip (where the tire mounts) and 275mm is 10.8" so you have a perfectly flat sidewall which is the optimum setup for handling, comfort and tire performance.

Um... did you read my post? "lowered Z"? "Raise it"?

Also, the 9.5 rim with 275 tire has already been addressed by someone else. I'm not a "mad drifterz". I track my car and go with what the tire manufacturer designed the tire to be mounted on.

 

275/35/18 might be a good idea, at least itll look better
