Speed Rating for Kenda 4.80/4.00-8 Bias Trailer Tire with 8 Galvanized Wheel

Question

Question:

Kenda 4.80/4.00-8 Bias Trailer Tire with 8 Galvanized Wheel - 4 on 4 - Load Range B Item # AM30010 The description mentions high speeds. How fast can a trailer be towed using these tires? What is the proper inflation pressure? I see the max pressure to obtain max carry capacity. What should tire pressure be if tires carry less than 50 of load capacity.

The Kenda 4.80/4.00-8 Bias Trailer Tire with 8" Galvanized Wheel - 4 on 4 - Load Range B # AM30010 has a max speed rating of 65 mph which is becoming more of a standard for trailer tires.

You always want to run trailer tires at max psi capacity which will be stated on the sidewall - for both tires mentioned above that would be 60 psi. The only exception is when the trailer tire manufacturer comes out with a table showing what different weights different psi ratings can handle, but these tables are few and far between which is why it's always best to go with the sidewall rating.

Answer 1

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

First, the DOT date code on a tire is 4 numbers. The first 2 are the week and the last 2 are the year. So for example if it was 2314 that means that tire was made in the 23rd week of 2014. There isn't a difference between a tire sitting on the…

Hello again Mark; as long as you don't exceed the 65 mph rating you can stick with a tire like the Kenda Loadstar K371 Bias Trailer Tire #AM10002. Moving to a larger tire with a higher speed rating is going to mean a fairly large size difference.…

That all depends on what the trailer tire manufacturer has tested and rated the tires for. You can either look for a speed rating stamp on the sidewall of the tire (it should be by itself in a little indention) or you can reach out to the tire…

Are the wheels on your TeeNee Trailer hub piloted or lug piloted? If they are lug piloted then you would only need to make sure the size of the pilot hole on the wheel exceeds that of your trailer hub. It does not need to match this or the wheel you…

Answer 6

The two tire sizes you referenced, 4.80-12 and 5.30-12, both fit 4-inch wide rims, but they differ in their overall diameter. A 4.80-12 tire/wheel when fully inflated will have a diameter of 20-1/2-inches while the 5.30-12 size will be just under…

Answer 7

For smaller tire sizes like the 4.80-8 that you mentioned the highest speed rating we have is 65 mph like the part #AM10002. This is in part due to the smaller diameter of the tire which means it will be spinning more revolutions at the same speed as…

Answer 8

Hey, thanks. You're not so bad yourself! Going to a larger tire size is possible but there are a few things to think about. Chief among these things is clearance. When going from an 8 inch tire to a 12 inch tire the diameter will increase by 4.4…
