285/75 Revo rolling resistance/load factor...

[MyCrush]

affecting gas mileage ?
Hi all, new to the boards here and 'search' doesn't fully answer what i am looking for.
I have a 94FJ80 that i plan on upgrading to above size tire based on the good reviews here and on TireRack, b4 i move to UT in the next month.
A few reviewers on TireRack state they have lost mpg<1-2> due to the 'rolling resistance' and 1 person stated that the buyer needs to be aware of the 'load factor' of the vehicle and choose from the 3 available choices in the Revo series as to which one is appropriate.

Any help here relative to experience w/ this tire noticing loss of mileage? And how about this 'load factor'? I havent seen anyone refer to this at all.

I sincerely appreciate any help that would be offered.
Great info on these boards btw.

You may lose a mile or two per gallon. Doing mostly highway driving, I don't think you will notice a loss. Throw in some city driving and you'll notice the drop in mpg. The 'load factor' refers to the amount of weight the tire will be carrying. Your FZJ80 is a tank, you need tires with a heavy 'load factor'. BTW, welcome to the site.

Okay...reality check time. You drive a vehicle that's shaped like a brick. Don't sweat the rolling resistance of the tire.

With a larger tire, you will lose a MPG or two in the city and gain a little of it back on the highway. It's not a Prius

I have the Revos on the wife's 80 -- I think it's a good tire -- many others here have it on their rigs...I think most will report favorably.

There's nothing unique about the Revo that would make the rolling resistance significantly different than any other AT tire.

Thnx guys !

I appreciate the input........and the sharp wit !

.......just learning as I go along.........

It never crossed my mind that the entire vehicle is ' rolling resistance ' , until I saw it here........thats too funny !

I've had them for almost 30K now and really like them on and off road. I think they are a great cross between the Michelin LTX and the aggressive MT/R's out there.

Something to consider is that your speedo will be off with the larger tires. Order the speedo correction gear from Slee Offroad (vendor sponsor top right of the page). Get to know Slee for great products and other board sponsors like cruiserdan at American Toyota for ALL your OEM needs. They are all great. The speedo gear is inexpensive and easy to install. It will almost correct the % difference caused by the larger tire.

So is the 1 to 2 mpg loss actual, or just perceived that way because of hte bigger tire and the speedo being off. I.E., are you guys still seing 1 to 2 mpg loss after the speedo correction.?

I don't have the speedo correction, but after I add 3% to the tripodometer and do the math, my mileage is in range with what it was on the stock tires.

Yeh, it just doesn't seem like it would effect the mileage that much for that amount of tire size change.

I considered the same thing. All my mileage recordings were done via gps. Assuming the gps unit is accurate...I'd concur with the slight loss in MPG.

Agreed - about 1mpg lower w/speedo correction gear.
