Tire weights

For all the Guru's on site, pardons if this has been addressed already. Got 45k on original tires and looking to get new. I understand that tire weights can wreck MPG. Looking at Hankooks at 44 lbs per tire, stock tires are quoted at 40 lbs per tire. Question is will 4 pounds per tire likely to tank MPG? Getting 14.5 to 16.1 mpg depending on right foot now. Will take all suggestions.

 

You won’t notice a thing.

 

not enough to worry about. 4 lbs difference on standard load rating tires will not be something you really notice. Now if you are going from stock alum rims and tires to a larger and heavier rim and tires that weigh almost 2x stock, you will take a hit.

Also depends on the type of tire. More aggressive tread and higher load rating will reduce MPG a little. Moving from the 32inch stocker SL load tires in all season or the at2 tread to a larger all terrain in E load will reduce by about 1mpg, and that is based on the new tires being a 33inch. Of course the larger the tire the more they weigh so 34 or 35 inch tires will reduce MPG more like 2MPG.

 

thanks, looked at a set of KO 2's on E rated tires and they are supposed to be 11 lb increase in weight. so likely see a decrease in MPG. thanks for the info.

 

I am looking at the Bridgestone revo 3 in 295/70r18, they are 55 pounds. I was going to go down to a 17” wheel in order to get a non E rated tire, but these are lighter than all the C and D options in 17”. Only concern is ride quality. I hate feeling every pebble in the road with my current E rated tires.

 

I have 65lb Ridge Grapplers now and am thinking about the Revo 3’s as my next set as well. The P-rated 295/70/18 Terra Grapplers are tempting but the durability of E rated tires is also nice to have.
