What is the Speed Rating for Karrier ST215/75R14 Radial Trailer Tire # AM10229  

As a general rule of thumb, trailer tires should be replaced every 6 to 8 years regardless of wear. Even though an older tire might appear to have plenty of tread left on it, dry rot and cracking can cause tire failure. I attached a link to a help…

Since the highest load range we offer for the 215/75R14 tire size is Load Range C the best option would be to go with a Load Range D 205/75R14 like #AM10235. This tire has a capacity of 2,040 lbs when inflated to 65 psi. You will want to determine…
