i just picked up a set of 315/70-17s at $147 a tire. they ride way better than the toyos that i had on it and work better in snow. they are only a C rated tire but i dont plan on hauling anything heavy so no need for E rated
local tire shop. i saw them on 4wheel parts for 199 so i called my local shop to see if he could match that. turns out he could beat it and there also happened to be a 50 dollar mail in rebate at the time too. so i pulled the trigger and also sold my set of toyos for 650 just the other day.
I really depends on tire size. I work in the field of acoustics and structural vibration. I just replaced Yokohama Geolandar LT285/55R20E with BFGoodrich LT275/60R20D. My original tires were Goodyear Wrangler Adventure 275/55R20. Here is my take:
Goodyear Wrangler Adventure 275/55R20 (35 PSI)
-Decent ride and good on dry or wet pavement
-Horrible snow traction on packed snow at low speed in pacrking lots. The tires were not much better climbing my driveway (7 deg slope) on light snow.
- Road noise (radio & ventilation system off) - 62 dB average over 10 miles at 35-55 mph.
Yokohama Geolandar G015 LT285/55R20E (45 PSI)
- Great tire on dry or wet pavement.
- Great ride on smooth roads and slow speed
- Stiffer than stock, as expected, and rode great on the highway with one exception
- The tires created a wicked bed bounce on segmented pavement in curves at 65-70 mph, so much that it would cause the truck to bounce out of my lane which prompted replacement.
- Road noise (radio & ventilation system off) - 59 dB average over 10 miles at 35-55 mph . A 3 dB reduction equates to a 50% noise reduction and ~20% perceived reduction to the human ear.
- I did not drive in the snow, but they are rated very high on TireRack.
BFGoodrich KO2 LT275/60R20D (45 PSI)
-Road noise (radio & ventilation system off) - 64-65 dB average over 10 miles at 35-55 mph. A highway hum from the tread is evident in the cab. It is present when slowing down too.
- Everyday driving is rougher than the Yokohama tires even with a larger profile and lower load rating.
- I am taking them back to check for road force since I get more vibration now.
- I have not driven in the snow, but ran these tires previously on another truck. They perform great in snow and on wet roads. Rated #1 on TireRack.
I believe the 17" and 18" tires will perform the best for ride quality. Unfortunately, the 20" ride quality will suffer regardless on a LT tire due to aluminum body, reduced vehicle weight, lower profile and stiffer sidewall. I had hoped for a smoother ride with the higher profile and lower load range but it does not appear to help.
