Question:

I have a small pop up I have to tow across the country. Currently I have 4x4 5.70-8 tires. I am looking to upgrade to something with a better speed rating and load range D. What tire would that be?

Hey Austin,

For a 5.70-8 tire size on with a 4 on 4 bolt pattern we offer a Load Range D, but don't have a higher speed rating than K (65mph). To get the increased speed rating you'd need to go to a larger size tire like 215/60-8, which would be quite a bit wider than your current wheels so you'd have to replace both the tire and wheels with something like the # AM98NR.

This would be 18.3" in overall diameter and 8.9" wide so you'll need to verify if you'll still have at least 3" vertically from the tire to fenders and 1" from the wheels to the frame horizontally. If you don't then the tires are going to rub when suspension compresses. This wheel and tire combo has a speed rating M (81mph) and Load Range D rating.

Hey Austin, how did the larger 215/60-8 wheel and tire combo work out for your pop-up? Were you able to get the clearance you needed around the fenders and frame? Your results could really help others looking to upgrade for better speed and load ratings.
