dggodden my rims are rated for 110 psi. I only have 3 inch clearance between tires so I would loose an inch if I went with the 85,s but I want to use my other marathons for spares so they wouldn't match up. what to do.
Differance between 80 and 85 is more than an inch. Been there. You will loose about 1.5 inches between tires. That was my last rig before Sailun came out with the 80 series tire. My new rig i am 2 weeks away from ordering the 80 size tire, not going to try and squeeze the 85's in its place.
