sorry for the late response. I've tried several times to set my site preferences to email me notifications but it never seems to stick.

Hope it's not too late, but no real drop in mpg, maybe 1mpg at most. And that's running 10ply E range - much heavier than the stock P metrics. 6 ply C range would be even less noticeable. We live in the NC Mountains now and average 19mpg tank to tank with 101,000 on the truck, even going up and down the mountains. We have 10% ethanol gas here so that doesn't help. Aerodynamic drag has a much larger effect than tires on this particular vehicle imo. I get better mileage running up and down the mountains at 60-65 (speed limit 60 on interstates here) on highways vs down in the flats running 75-80.

When I lived in Kansas City (when I first got tires) I lost 1mpg (down to 17 avg) when I swapped the tires on, but it's windy there and everywhere you go you're running 75-85mph.

Hope that helps,

Hello,

I saw your post about the Kelley TSR tires that you have. I am looking at getting a new set of tires/stock size and have been looking hard at those ones. I read about your reviews, but one thing you didn't mention is MPG. Did you notice any significant change when you switched from stock to the TSRs? Thanks in advance!
