I'm finally getting some BFG A/T KO tires for my 98 tj this weekend.
I have 3.73 stock gears and, I'm stuck on deciding which size to get.
I prefer the look and clearance of the the 31's of course but, I'm
thinking the bigger tire will make the engine work a little harder,
making the already dismal MPG worse. Is this correct? I currently
have the GSA 30 inch tires and fifth gear is just tolerable.

Also, I don't need huge ground clearance, but I do want good snow
traction. With the weight of the jeep in consideration would the
wider 31 x 10.5" size be better or worse than the 30 x 9.5"?

Thanks
Jeff

 

Skinny tires give better traction on snow-covered streets than fatter tires
do, no doubt. :)

I went from the BFG 31x10.5 that measured close to 10.5" on the tread to
BFG 33x9.5's that measure 7.5" on the tread and the improvement in
winter handling was extreme.

With the 10.5's 40 - 45 mph was about tops on the highway in 4x4 and
4-6" of snow down. It would get on top and lose grab on the road any
faster.

With the 9.5's I can easily follow along with transport trucks at 50- 60
+/- mph in 4x4 and have no control issues at all.

Off road on sand pit wall winter climbs, the guys with 10.5's and front
and rear lockers can almost keep up to me with my open diffs.... ;-)
