So I've been reading alot of about tire pressures and their impact on rim protection. Just curious what pressures you guys are running your 245/35/19 + 275/30/19 tires at. Thank you.

So lowering or raising the recommended psi helps? The other day I my flat light came on went to the flat fix shop and he discovered a nail in the tire while i was there I made him balance my tires and he informed me that I was driving around with about 7 to 8 psi low on each tire I didn't even know that so naturally I told him to fix them but i hate how the ride feels now it feels bumpy and less absorbing to pot holes

I'll take a bumpy ride over a bent wheel any day of the week. What was your pressure before, and what is it now? Also, what wheel/tire set up are you running?

I recommend maintaining tire inflation pressures at or no more than 2-3 psi above that recommended on the driver side door jamb.I do not recommend running lower psi than the same sticker lists.

take vehicle weight 5 series 4000lbs/4 =1000lb per tire load
take 1000/load index... so 1000/1565(hankook 275/30) =.63
take .63* max tire pressure.. .63*50=31.94psi...
So minumum tire pressure is 32psi
I would run 35-39 all the way around!
