I have a couple of quick questions. I just got a set of 295/75/16 hankook mt's. Their max psi is 65. Discount tire installed all four of them at about 35 psi, but they look a little low to me. I know keeping them too low will also wear them out quicker. Higher psi will give slightly better gas mileage. But inflating them too high will make them ride pretty rough and make them easier to puncture. So what in your opinion and from experience is the best psi to run for these with a 65 psi max? maybe 50 psi? or around 40 psi?
Also another quick question: what effect will cutting my exhaust behind the axle have? I have a 14" magnaflow muffler, but my tip is just getting rusty and I'd like the cleaner look without it. Will it make the sound any/much different? Also, will it hurt anything like the spare tire or need another hanger to support it?
Thanks in advance guys
