Should I be concerned? (tire question)
Our Jayco came factory with Duro 185/80D13 bias tires rated at 1660 lbs at 65 PSI. I recently purchased 185/80R13 Load C Maxxis M8008 Radial tires rated at 1480 at 50 PSI. Should I be concerned?

- I always go a more heavy tire than a cheaper one
- Another Maxxis Reference.
Can I go up in load capacity?
Answer: Yes. It will not harm your trailer to go from a lower to higher load rating, but you should never go from a higher to lower load rating.

FE - I also scrapped my OEM Duro bias ply's for radials....I think the TT tracks better with radials than it did with bias ply tires. Also rides better with less bounce, and adding shocks made a huge difference along with that.
In general, mfrs spec tires that are barely capable of holding the load, so going up in load range is desirable/advisable. In this case, the OP seems to have plenty of tire capacity in light of his GVWR....I would think the OEM saved a few bucks by going bias ply instead of radial.
Not sure what the universal obsession is with load range without considering the loaded weight of the trailer. Too many it seems are quick to parrot what they read here without understanding the "WHY" of it..... - My Forest River Flagstaff rated@ 6500 lbs came with load range C tires. I changed out to load Range E. Peace of mind..............Priceless!!!

You will be fine!
Yes, the GVWR of the rig is 4,750 BUT you have 4 tires... so 4 x 1480 = 5920, you have more than enough tires to carry your fully loaded trailer even though they are not rated as highly as the bias ply that came from OEM. To be safe, next time you are out traveling with the trailer loaded, gas up at a Pilot or Loves and take a qucik trip across the scales to see what your TT tires are carrying.

You will be fine with the C Maxxis. Keep them pumped to 50 psi max while on the road or in storage for max load carrying performance/less rolling resistance and max long term reliability.dieselenthusiast wrote:

PackerBacker, when I searched online for 185/80/13 tires, the Maxxis appeared in the search engine in several places and seemed highly rated. Most websites did not specify the Load Range since Maxxis only manufactures that size in a C Load Range. I obviously failed to be more detailed in my search and assumed that all 185/80/13 were of the same load/quality tire. Upon arrival, I immediately noticed the difference.

It would seem that Maxxis only starts with D rated tires in the 15" version, I never knew that.
... Eric- The Maxxis warranty will not cover tires with less load capacity than the trailer's OE tires. Less is never better with any RV trailer tire replacements

FastEagle - Who sold you these?
If you trailer came original with D's I would have put at least D's back on... beemerphile1 wrote:
Factories don't spec any higher than they absolutely have to. I would never install weaker tires than the factory installed.
Truer words were never spoken.
You should be going up in load range, not down.- Factories don't spec any higher than they absolutely have to. I would never install weaker tires than the factory installed.
