I'm trying to get the tire pressures right on the R7s on my 914/6/gt. Running 275x35x15 and 245x40x15. I initially started at 22 shooting for 27 hot but I think they like to be run a bit lower than that.
I'm nowhere near what Hoosier recommends though. Any thoughts? |

your still too high of a pressure at 22
I think we are 20 or 21 cold what is your vehicle weight? also those tires are really large to heat up at on a light weight car. The tire is designed to cover such a wide range of modern performance cars. it has to work well on a 3000lb corvette and is designed more for that than it is on a 2000lb 914 which motor? (hp? are you) we had to work with a hoosier tire tester/pro and the factory engineer to get 7's to work. Ultimately we found at our weight that even with a 225 the car was too light to heat up the tires at our low horse power. we switched to A7's because they heat up better with a light car. have you taken any tire temps? |
