Intriguing tire for the E9x: 295/25-19 Viper ACR Kumho front tire

Saw the Car and Driver article on the Viper ACR that just hit the website (cool article, you should check it out) and noticed it runs a 295/25 front bespoke Kumho to generate its 1.15g of skidpad grip.
E9xM could probably run these square on 19x11's with the right offset choices (they're only 24.9" tall!) and 10.5's would almost definitely work

Price sucks at $360 each, but for ultimate performance this might be the fastest 200tw tire available right now for these cars because you can put so much rim under it and still fit it under the front fenders thanks to the short diameter

I always appreciate new tire options, good find.

That was a great article. It's such a pity the Viper has disappeared!

These should fit for sure, but I don't think there are any nice off the shelf 19x11 wheels with appropriate offsets. I have 18x10.5s

I think you'd either need to use the Apex (mismatched PS7's on sale now for almost hafl the cost of the tires, lol) and adjust with spacers, or the F8x Volk, or custom, or just use a 10.5 lots of those out there

I have a friend with an ACR and those front tires are the single reason that he has considered selling the car. They provide phenomenal grip and performance BUT only last one track day (sometimes less) making the cost to run the car very high. He gets a 2+ days out of the rear tires but those fronts are gone fast. 200tw is kind of a joke. Those things are more like 60tw at best.

There aren't any other 295/25/19 R-comp or better tires on the market. I think some viper guys go to 295/30/19 Hoosiers in order to bring down running costs. However that results in an increase in diameter (not the end of the world) and a car that can no longer be safely used on the street.

You can run a 295/30-18 over the acr ceramics with the appropriate custom wheel. Toyo for instance makes a tolerable streetable rcomp in those sizes

True but the performance of the Toyo is sub-par compared to the Kumho's. Those Kumho's are awesome, they just don't last. It puzzles me that Dodge chose to run a 25 series front tire on that car. That sidewall height is so damn thin but somehow it works.

This makes me want to pickup a couple of the PS7s in 19x11 et25 and run staggered Toyo R888Rs: 275/35/18 fronts and 295/30/19 rears.
