So.. I found one of the few sporty tires for 14" rims for my 914. Falken Azenis RT615-Ks. 195-60-14.
So far, I really like them. However, I can't seem to tell a good pressure for them at AX. First even started at 35 cold all around.. felt ok, and kept bleeding down to 35 as they heated up. Car felt good, but did feel as they heated up I was losing grip, hence the bleed downs during the day Second event, didn't check cold (slow brain) but bleed them down, hot to 32ish. Couldn't really tell if they were better or worse than 35 hot... My previous 914 and R comp experience was 205-50-15s (smaller sidewall) of Yoke A008, A032rs, Kumho Victoracers, RA-1s. For those, I never ran more than 30hot. What could be skewing my memory/preferences is the last 3-4 years I ran a stock 1987 944, 215-60-15s Fuzion xxxx's and they really felt good at 35 hot all around. Thoughts? Should I be closer to 30 hot with these too? Perhaps I fear too much sidewall flex for the 60 series tire... |

This is highly dependent on your ambient temperatures, how stiffly the car is sprung, horsepower, weight, etc. But for me, with a stock 1.7 or 1.8, I run in the neighborhood of 23 front and 26 rear, HOT. This may sound rediculously low, but with such a light car with very little power and not super-high spring rates, you want to make the tires do some work. I found with these pressures I was getting a fair amount of rollover on the tire, indicating a pretty good contact patch. On really hot days, I've even gone lower than that. I run a little extra psi in the rear to help coax the rear end around since it's damn near impossible to produce any kind of throttle-on oversteer with a stock motor. Keep in mind this was also with 205/50/15s. But don't be afraid to experiment.
Also, this is a very basic indicator, and isn't as scientific as checking tire temps, but you can check your rollover triangles at the top of the sidewalls of the tire. You will ideally be looking to get the tires wearing right near the top of the triangle if your pressures are right (and you're driving the car as hard as it can go). |
