Tire Pressure Question On the 99 Z28 I just bought it has 275/35/ZR18 tires.
What would be a good tire pressure to run in these tubeless tires? 33-36 PSI range?
Thanks for the help

I would look for wear after a little while and if the outer edges are wearing sooner, then it's too low. If the middle is wearing sooner, too high.
If you want to really know, the temp across the tire should be the same after a good drive on them and will indicate if the wear is even. If you know someone with a pyrometer, (you know, the laser temp tester) check the temp across the face of the tire. You can actually buy one for under $50 now. The idea is to have consistent temps across both sides and the middle. That is the process used when running r-compound tires in Auto-cross to ensure they are wearing evenly and you're not killing tires by running a pressure too high or too low.
