225 or 245, best for stock 8" wheel?
Quick question if I may.
Dont compete with this car, so the answer is not really critical. Plan to autocross for fun, maybe HPDE if my schedule will allow.
From what I know you want the tire width to be even with the wheel width. Most cars that have 245 tires mount them on 8.5' or wider wheels. Is the "extra" grip afforded the 245 versus the stock 225 offset somewhat by the narrower tire to wheel ratio? Or would I or anyone even notice the difference. I like the tight feel the car has an if a too wide a tire (per wheel width) is used it will cause the car to feel mushy with steering inputs.
I know, a 275/35R18 on a 10" wheel would be great, but just curious what would work best with the stock wheel.
Thanks

245 is the widest you can go on stock wheels.
But it really depends on what tires you are planning on running and at what pressures. As far as mushyness.
generally I will recommend a 235 on stock wheels, The 245s felt too loose for my tastes for the setup that I run.

From what you say you know the answer. Still, 'better' and 'best' is a fuzzy science here with a lot depending on the tire and a lot of combos work with + and - attributes for each.

I loved the 245 set up.
I went back to 225 because the diameter is smaller. I don't like it. It's more stable with the 245's.
I went to 225's to see if I can drive on the street since they are .8" lower.
If it works they I go to 17" wheels. So far I can get around but never over any speed bumps.

am a bit confused..
as talked about..
225 / 45 18 is 25.9 in dia.
245 / 40 18 is 25.8 in dia.
these sizes are what people do on a stock wheel.. as the dia controls the speedo error..
what aspect ration are you running??

My last 2 sets of tires have been 245/40. Love 'em

Kuhmo Ecsta MX 245/40 18s are what I've run the last two sets. Very good grip in the summer. Much less expensive than most. Better than the stock Potenzas. Think I paid about $150 each last time. Decent mileage for a summer tire at around 30k. They take a long time to warm up when it's cold out and forget about snow.
My wife's MS6 has Pirelli PZero Nero MS that give a nice smooth ride and decent grip for a MS. This is a great all season tire at about $168 per tire.

Thanks for the headsup. Been looking for tires with a similar treadwear as my old Ventus RS-2s (because no one ******* sells them in my sizes... ). $125 for tires that usually cost $200+ is REALLY cheap.

Just go with 245's.

For racing, you want a 225 on a 8.5 - 9.0 wheel. This is to minimize the side wall flex. This would be for a Hoosier or Hankook or Toyo race compound tires.
9" works with 245 nicely too.
Get the 245's as your grip increased quite a bit. Mount them on 9's if you can. 8.5 would work but 9's is best.
