What tire pressures are you Kuhmo v700 tire owners running frt and rr. I'm trying to get a general idea of what other people are doing with the Kuhmos

Thanks Mattj

 

for 225/50F & 205/50R I run 41~43psi F & 45~50psi R for autoX.

yoshi - who hopes this kinda helps

 

high 30's all around.

generally 38-38.

 

Usually 40 front (225's), about 37 rear (205's). Higher pressures in the back will allow the car to rotate better, but I didnt like how my car was handling slaloms, so I usually go with 37 rear. Experiment to see what you like

 

39 F (asphalt)
41 F (concrete)

40-44 R (depending on surface, speed, and amount of rotation desired)

 

On RE-10's I ran 38F / 38R cold ... ~41 hot

 

225/all around was 42/f 48/r thats for AutoX

for tracks I decreased each by 5 at first and kept reducing depending on how the car felt.

Last year I was running high pressures (low 40's), but I lowered the pressure to mid 30's this year and I like it better. In the August edition of Grassroots Motorsports they test DOT R-compound tires. They ran the Kumhos at a high pressure first, resulting in disappointing results. They lowered the pressures and had much improved times.(On a road course, not an autox). I can to this same conclusion from my own autocrossing experience. I think the sidewalls of the V700 are stiff enough not to worry about tire rollover. I usually autox on semi-rough ashpalt, outside temperatures in the 80-90's during the summer. Of course, tire pressures depend on surface, outside temperature, driving style, number of runs, etc. etc. The best is to use your own experimentation.
