How Does The Kenda ST235/75R15 Off-Road Trailer Tire KE68JR Compare To The Rainier Equivalent

Updated 08/11/2025 | Published 08/05/2025

Question:

I am currently using an Rainier Apex ST235/75R15 Load Range D, Speed Rating M on my Coleman Rubicon travel trailer. Right now, I cannot find this tire in the US in a load range D. Is the Kenda KE68JR an equal replacement for the Rainier Apex? The specs look similar including the load rating in pounds and both are off-road capable. I wanted to get your expert thoughts if you are familiar the Ranier brand. thanks

Hi Charles!

I am also having trouble finding the Rainier Apex ST235/75R15 tire in a Load Range D. I found the Load Range C, but the higher rated D is proving to be quite elusive.

That said, I can't honestly say I have any personal experience with the Rainier tires as we do not carry them at the moment (that may change in the future). I know they are used on a lot of the offroad style campers/trailers and people definitely like them. From the specs I found though, I would say the Kenda ST235/75R15 Radial Off-Road Trailer Tire - Load Range D # KE68JR is pretty comparable.

This will have the same 8 ply sidewall, a similarly aggressive offroad tread (a bit less stylized though), and a higher Q speed rating of 99 mph (I don't think anyone should be going that fast with a trailer, but that's just my opinion). It does have a slightly lower capacity of 2,860-lb at 65 psi, whereas it looked like the Rainier had a 2,910-lb capacity at 65 psi.

I can also say these are easier to find and we go through a lot of them, so getting replacements looks like it will be quite a bit easier.

Have you put enough miles on your current Rainier tires to wear them out, or are you wanting a spare?

Thanks for the reply. We have probably put between 20 and 25 thousand miles and they were made in 2021. My plan is to replace them before winter sets in so that they are ready for our early year trips.

@CharlieS That's a good amount of miles! I tell people to change trailer tires every three to five years, depending on milage, so you are getting to that point. Do you do winter camping? I have been interested in that for a while. Being a large human, I don't particularly like the heat. The Russian side of me likes the cold though. : P

@LazerS not particularly. We try to stay above freezing although we have been in snow flurries a few times. We do like fall and spring camping the best

@CharlieS Makes sense. Fall out here in Missouri can be very pretty, so maybe I will try that before going full winter camping. Let me know if there is anything else I can help with!
