Any issues with this rim/tire combo?

[Sesshomurai]

I got a new set of wheels and tires for my track event this weekend and need advice.
It's not the perfect staggered setup, but what I could find on short notice was:

2 Hankook Ventus V12 Evo K110
255/40R19XL 100Y VSB

2 Hankook Ventus V12 Evo K110
285/35R19 99Y SBL

Both on RTR 19x9.5 rims.

The only difference from stock is the 9.5 wide rim in the front. Will that cause any problems?

thanks.

Would imagine you would be fine!!

There's a guy on SVTP running RTR rims and stock size tires. ALLKHEINZ I think.

Yeah, the front tires barely fit, but their snug and the back tires are a bit too wide, but they also fit snugly.

I think after this weekends track day I will move these tires back onto the stock rims and go with a fully square setup on these 19x9.5, with 275x35x19 tires. Does that sound reasonable? Or too wide still?

That would definitely work. Though I'd probably run 285/35 or if running square, but that's just a preference for a taller and wider tire. I definitely think 255 is too narrow for 9.5" rims. I think they're too narrow for the stock 9"!

If you do run square, I'd suggest going to a rear sway bar that's equivalent to about 22mm, or adjustable to that range. JMO.

Cool. Thanks Grant!

So I have the 255's on the front now and will be at the track for 2 days starting Monday. I will move to a 275/40 front and 275/35 rear afterwards (for this wheel set), but do you think it's safe with the 255's on the front for now? I realize they will wear poorly stretched on this rim. It was all I could get on short notice.

I don't think there's anything unsafe about the sizes mounted since the manufacturer lists those size rims/tires as compatible. You still need to monitor your hot temps, tread profile temps and wear patterns, etc. to be safe IMO.
