    Last winter I bought 4-235/85/R16 new tires for my 1986 K20 Chevy 4x4 to plow snow with. Of course 3 days after mounting the tires on the truck, the frame gave way and I had to scrap the truck. I replaced the 1986 with a 1998 K3500 one ton single rear wheel 4x4. The one ton 4x4 has 245/75/R16 tires which are the stock original size according to the book. The tires on the truck are well-worn and need replaced. Does anyone know if the new tires from my old '86 will fit on the '98 without rubbing the fender wells on the front end? They are one size narrower and are 85's instead of 75's and are 1 inch taller overall than the 245/75/R16's on the truck now. I'd like to know if anyone runs 235/85/R16's on a late 90's K3500 without problems. Thanks for any info in advance, Don

    I have a 98 reg cab SRW K3500 4x4 with new 245/75/16 tires on it. I have the black plastic wheel well trim as I'm sure yours does. I just measured from the the tread part of the tire to the edge of the front part of the wheel well trim and its about 2 3/4". I have about 6" from the top of the tire to the bottom of the wheel well trim. I have about 3 1/2" from the rear part of the tire to the rear edge of the wheel well trim.

    I think you are going to be close at the front edge and I'm not sure how close you will be in a turning situation. Of course if there is only a 1" difference between your worn 245's and the new 235's then the difference may not be as much as you think. My truck doesn't have a plow on it so I don't know if it would make a difference in side measurement with a plow on. Hopefully my measurements can help you out even if I can't give you a direct comparison.

    I took my K3500 to the tire shop this morning and they removed my worn out 245/75/R16 tires and mounted and installed my 235/85/R16 tires for me. ($62.84) New valve stems and valves included. I took the truck there with my Meyer C-8 blade attached to be sure there would be no clearance problems. They said the 85's would fit and they were right! It's nice to have tires with tread on them again. Don

    235's arent those kind of short?? My 2000 2500 had 245/75/16's stock, but I put 265/75/16s on it now and looks sooo much better. Alot of guys run 285/75/16 on the Chevy and GMC's.

    They should be around 31" tall... taller than his stock tires but one size narrower. Should be a superior tire in the snow.
