I tore the sidewall on one of my stock tires, so I'm going to take this opportunity to upgrade to some BFG TA KO2s. I had them on a RWD Dakota and the difference they made on dirt and snow was incredible. I've got some questions about the sizing and tire pressure though.
My truck is a stock Ram 1500 4x4 Big Horn Quad Cab.
First, the stock size is 275/60R20, but I've heard 275/65R20 might work too. I wouldn't mind having the extra half inch or so of sidewall. Is there anyone running 275/65R20 on a stock truck? Does it rub at all? What does everyone else think?
The other big question is pressure. Both of those tires have much higher maximum pressures than the stock tires and they have a different load rating. 65 and 80PSI respectively. Is 36-40PSI OK to run? Should I go higher? Is the TPMS going to be an issue if I do?
I've also been considering going with 18" rims (same tire diameter). The 20" ones have always seemed to be a little on the low profile side. 18" might offer better protection from pot holes, rocks, etc... I'm thinking I'll probably stick with 20" rims for now though and only change them if I have a good reason to.
