Tire sizes

Asked by Jan 25, 2016 at 11:54 AM about the 1999 Dodge Ram 1500 4 Dr ST 4WD Extended Cab LB

Question type: Maintenance & Repair

I use the truck for snow plowing and currently
have 265 R70 16 tires on it. I believe original
equipment was 245 70 16's.  Tires, especially good
used tires are hard to find in the 245-265 width.  
Would 235's work?  What are the consequences of
going to a 17" tire?  Does there need to be
adjustments to the engine when increasing tire
diameter?

Your 265 R70 16 would be your best bet for plowing. The 17" tire you would need new rims. They can go on there, usually the profile of the tire they would match up to the tire size that would go on the truck. So diameters of the tires would match original tire size. Then you speedometer would still be accurate. 235 in my opinion is too small for the truck.

I plow snow and 235's would not work well in my opinion. I run 285, 70/17's on my Ford F150 and they work well. Small tires will reduce your traction, load carrying capacity and ground clearance. I don't know where you are tire shopping but I find a good selection of new tires in your stock size as well as 255 and 265 tires. 17's have a great tire selection but don't raise your truck up too much as it will screw up your snow plow angles.
