Question 170x80, the good, the bad, & the ugly-???

OK, my front had begain to dish a bit and as has been suggested I put a 404D 110x90 on... Worked out good, speedo more correct, think the odometer may be a tad short though, no prob... OK what will I gain or loose with the 170x80, is there any clearance problems, how is the fuel milage going to be effected..?? I can't see any O.D. difference to amount to anything, 135 vs 136mm, don't seem enough to change the gearing to amount to anything... I could be wrong though... What are your experiences with these tire size swaps..??
Thanks and have a good one...Old Dog...

It will be a tight fit with just enough clearence. When the shop put my rear tire on they had to deflate it first to fit it in. I went with the bigger sizes for front and rear. I haven't noticed a change in gas mileage. I did notice better handling and more stability.

Diannia has a 170 on hers and did say it lowered her RPM's on the highway but it will take away from your low end off the line.

I'm not sure about the RPM's. I'm pushing a little over 4500 at 70 MPH

My 05 is lowered 2 inches and it fits fine. Handling is better for sure.
