Are Same Size Tires With Different Load Ranges Okay to Use

Question

Question:

Hi, Iam a etrailer.com customer. I own a Dutchman Kodiak 24RBSL. I just bought 2 new tires 205/75/R14 load range D max. pressure 65 psi for one side of the trailer. The other side has 205/75/R14 load range C max. pressure 50 psi. Is this combination safe as long as I keep proper inflation in the tires and do not overload the maximum weight of the axles? Thank you.

Thanks for being a customer!

As for your question, even though your tires are the same size, ST205/75R14, using one with a load range of C such as # AM10234 and one with a load range of D such as # AM10235 that have different psi ratings means that the tires will wear unevenly and it is also possible the trailer won't track as well behind your tow vehicle because one side will build up more heat due to the load range D tires having a different ply rating.

Due to that I do recommend having the tires with the same size and load rating on your Dutchmen Kodiak 24RBSL.

Both metals help to protect your tank. There are only a few people that have a preference and it is normally based on aluminium being lower on the Galvanic Scale than magnesium so it produces less driving current between the anode and cathode (tank).…

That's a good question, and the two tires are very similar, so you can absolutely replace your Kenda KR35 with the Kenda tire you asked about, which is the following: - Karrier ST205/75R14 Radial Trailer Tire - Load Range C #AM10234 This is the…

Answer 4

Different size and bolt pattern wheels that take the same tire size will have different psi ratings. If your existing wheels are rated for 65 psi then it is less likely that they would also be rated for 80 psi which is what an ST225/75-15 load range…

Yes, you always want to have the tires on the trailer at maximum PSI rating of that tire, in your case, 95 PSI. Anytime you run a lower PSI, it significantly reduces the load carrying capacity of the tire. If you were to run a lower PSI, the thicker…

Answer 6

A higher load range tire has a higher ply rating but it will also produce a rougher ride and could have a psi rating that exceeds the capacity of the wheel or, more likely, the valve stem. The size you have now, 225/75-15 load range C, is rated for…

I can end this debate for you real fast! Trailer tires, which will have an ST in front of the size, should always be inflated to the maximum psi indicated on the tire. Trailer tires usually do not have a recommended and maximum psi indication so I am…

It looks like you're checking out the ST205/75R14 sized tires, and when it comes to highway driving, particularly on that long of a stretch, you definitely want to go with radial tires over bias tires, depending on the load range you need: - Load…

I walked out to our warehouse and looked at the Kenda Radial Tire, part #AM10234. The tire is manufactured in China. The time stamp on the tire read 0911. This indicates that the tire was manufactured in the ninth week of 2011. You can find this…

Answer 10

You can potentially use new tires and wheels on your trailer as long as there is clearance all around the existing tires for the larger size. Going to a 13 inch like with #AM31985 you will need at least 1.8 inches clearance above the existing tires…

Answer 11

The Kenda Karrier tire #AM10235 you mentioned isn't a bad tire by any means, but it's made in China, but it is made using the same equipment as tires made in the USA and is made to USA specifications. The Kenda Karrier #AM10235 currently has…

Answer 12

From what I could find it doesn't look like there is any kind of 6R ply rating so I would guess that the R either stands for "rating" or possibly radial tire like what you find with the Karrier #AM10234. I spoke with our residential…
