I'm looking seriously at the PS2s 245/35 front and 255/35 rear, still got 3/10 to wear off the current tires. But if everyone is stretching 275s on the rear I may go that route. I suppose I can live with a little more understeer as long as the corning G's are improved overall.

Any horror stories I should know about with stretching too wide of a tire onto a rim? I'd hate to blow a tire going around the "bowl" at New Hampshire Speedway.

EDIT: What have people been stretching onto the fronts? 245 is acceptable for an 8" wide rim for most tires from what I've seen. Anybody take it wider then that?

 

The car already rides rough enough as is. Make sure that going with wider tires isn't inadvertently giving you a shorter side wall which makes the ride that much rougher.

 

Anybody done 245/35/19 in the front with 245/40/19 in the rear? Circumference on the front is pretty close to stock so I think VDC would be fine. That combo in the Kuhmo Ecsta SPT tires = dirt cheap and the same tire all around. Pretty good reviews.

 

would be a good option, and will reduce some of the factory understeer inherent in the coupe

 

What's wrong with Wes G's idea...
"i have stock 19's with 245/40/19 TOYO T1R's front and rear and im fine."

Can't you rotate them if you use same or are they unidirectional?

 

The stock setup is staggered front and rear, and running the same size all around can cause issues with the VDC. While wes g may not have any problems, that doesn't mean no one else will. Plenty of people have run into issues with nonstaggered setups on the coupe because of the factory stagger. He may also not be seeing the issue because he is not pushing his car to the limits where the VDC will start playing a roll. Rotating is overrated anyways since it doesn't really reduce camber wear from the front to rear, and the front wheels are 19x8 and the rears are 19x8.5. I see you advantage to this setup compared to stock or a 245/35/19F245/40/19R setup.

 

Other than doing the wrong thing

No, you can't rotate them. The tires are directional, and even though your tires are the same size, the wheels are not. You have 8.5" wheels in back and 8.0" wheels in front.

Yeah, that's the other thing I was hoping for.

 

question.. what are the tire sizes from the factory on the stock 19s? shouldnt that be the staple of what to use?

 

225/40/19 and 245/40/19. Some people thing they can get better performance by sticking wider tires on them or so they can rotate their tires. Not a good idea IMO

 

EDIT: Bah you beat me to the punch :/

Stock size is 245/40R19 on the rear and 225/40R19 on the front.

Oddly enough the stock soze isn't anywhere on this thread.

 

Performance is a relative thing for most people. Performance could mean just for looks which I think is what a lot of people are going for.

Now myself, I'm going for handling. Just a few more fractions of a 'g'. Every fraction of a second counts. When you push the wheels to 100% on the track the typical rule is the more rubber in contact with the road the better.

 

Yes, and to a certain extend that is okay, as I've stated in the thread, when people start putting tires that are too wide for the wheel however, performance can decrease to the bulging sidewall, IE 275/35/19's on a 8.5" wheel

 

Well it would be great if anyone had skid pad tests with 245s and 275s of the same brand on the 8.5" rim. While keeping the same size on the front.

Humm could provide for an interesting search on Yahoo. I'll see if I can find anything similar and report back if I actually do find something, though I doubt I will.

Anyone got the spare $$$ to get some empircal data?

 

Going outside of the manufacturer's acceptable safe range is enough of a reason for me to not try it.
