I am coming from stock setup with Michelin Defender LTX M/S. I will be putting Pro wheels on and bought Bilstein 5100s that I was going to set to 1.75 with 1" rear springs. My plan was to run Cooper AT3 275/70/17 in C load yet for some reason I can't find them, even though some guys claim to be running them.
I was hoping for a slight lift with 275s to fill in wheel wells, but options are just too limited and I don't want to sacrifice ride and mpg with a heavier tire. I'm now considering just putting the bilsteins at .85 up front and sticking with stock tire size.
The Michelins have honestly been acceptable for the off roading that I do, so I am thinking about the Falken 265s in SL. I know it varies, but should I only expect a marginal decrease in MPG? I am hoping to stay under 1 mpg loss. Also in theory, these should be easier to balance compared to a C load, correct? I had big troubles with steering wheel vibrations with the stock Dunlops. After several balancing attempts from the dealer, the truck finally went to the regional tech office for the Michelins and balancing. I think my 4Runner is just a sensitive little guy, so I am worried about switching up tires and having issues again.
