Default Understanding tire size for touring car

I am looking to purchase foam tires for my Tc4. GRP makes 26mm, 28mm and 30mm tires. What is the norm size wise? I am not sure which ones to get. Thanks

I'm not too familiar with GRP Tires, but first you need to be sure you're not buying Nitro Foam's. These typically come in 26mm Front and 30mm Rear, and are listed by Shore Rating. A Higher Shore Rating = Harder Tire.

Indoor Carpet Foam tires are usually 26mm and 28mm and are listed by color for Foam Softness/Hardness. All brands are somewhat different, but a general rule of thumb is, darker color = harder foam. The most common are Pink and Magenta compounds.

Before you drop money on tires, check with the other local racers at your track and find out what brand and compounds they are running. When you go outside of the norm on tires, you could easily end up wasting your money.

Also check if there is a truer at the track you can use....Out of the box tires are normally are cut down in diameter to reduce "chuncking" and side wall flex....I ran them at 2.2" for touring car

I was told one time GRP and Parma use the same foam so the colors should match between the two...

I believe (don't have box in front of me) that Parma Pro 53 say on the box "made by GRP for Parma." If not correct, somebody with a box can post the correct wording.

Gotta check with the club, dude. In my club, we run indoors on carpet, but we use the 26mm nitro tires all the way around the car. Usually 32 shore in the rear and 37 to 40 shore up front.

EDIT: Just realized that this zombie thread is 5 years old.
