New here. Don't really like the Goodyear OEM tires on my new truck(2016 Sierra SLT) Just bought a Suburban for my Daughter-n-law which had Premier LTX 22's which are a great tire. So I am thinking I want the Premier LTX's for my truck which I don't plan to take off road. Stock size 275/55/20 I am thinking of going to 275/60/20. The diameter would increase from 31.7 to 32.9". The ride should be a little better. The speedo will be off a few MPH. The 60's are only 1lb heavier than the 55's but would still be 2-3 lbs lighter than the Goodyear's which is a good thing. Anybody see anything wrong with my thinking?
