Tire pressure

35 all away around good? Toyota says 30 front 35 back that doesn’t look right to me? 20 inch wheels

 

Are you driving a soccer mom mobile? If you are driving a truck, bump em up. Since I tow a lot I'm in the 35-38 area with my 18" Michies. Tires seem to be wearing great and wife doesn't bitch about the ride.

 

I usually ride around with 35 psi on all four wheels.

 

I run 38 front 35 rear for even tire wear with the stock 20 inch P rated tires. Rides a little harsher but no cupping on the front tires. Truck is rarely loaded to the max.

 

Here is a great tool for getting air pressure in the ballpark when using larger/smaller tires or tires with a different load rating from stock

 

My 2018 Platinum says 30 front and 33 rear with the P275/55-20 SL tires. About 2,250# capacity per corner at that pressure.

Most of the LT tires will want a minimum of 35 psi, per the pressure calculator provided. From what I’ve seen on this forum, most folks run between 35 and 40 psi anyway…
