Almost hate to ask this.....

but has anyone seen or possess a Load/Inflation table for WestLake tires?

I know or suspect most run at max for their given type, but it would be good data to know at what psi you can run with what weight.

It's not my intention to discuss the quality of or reputation of WestLake tires or other so called 'China bombs'. The rig came with these tires and I'm going to use them until there comes a time when I don't want to use them.

Thanks in advance.

If you are needing it for a SL309, here you go. If a different tire, you should be able to find it there on their website:

Mine are CR class and the only info I can find is on the WestLake Philippines or Dubai sites.

I spaced the actual tire label, but will get it tomorrow.

If you are looking for their ST tire line specs I was never able to find them on the Westlake website.

I had your luck as well. Mine are Westlake CR960A ST235/85R16. Also advertised as Goodride.

I'll keep looking......

Gotcha. Lionshead (who is the company that provides a lot of Forest River products tires and wheels) have them on their website:

Maybe this will help:

Westlake Radial Tire

Many tires (regardless of brand) just about have the same load/inflation table.

One thing to keep in mind is that each tire may have a different amount of weight that it carries. On my last trailer that I had weighed at a rally, the left rear tire carried almost 800# more than the tires on the curbside. In my opinion I would put the tires at max inflation and leave them there.

Underinflation causes problems. Inflate all to 110 and leave them there.

Each tire is rated at 4079 lbs at 110PSI. For my rig, that is 16,316 lbs of carrying capacity.

Hooked up, on the scale, I weigh 12,440 lbs on the trailer axles. That's half loaded (some of my clothes, all of my tools and dinnerware/cookware, full propane, full water, no people/pets/food).

16316-12440 = 3876 lbs of unused capacity for those tires.

Over inflation is just as bad as under inflation. And we're not even talking about the amount of bounce a fifth wheel is subjected to with tires that are hard as a rock.

If I can find a load/inflation table, I might get more miles out of those tires, less of a chance of a 'tire bomb' event, and less wear and tear of the coach.

In the absence of that information, I run max psi.

Unless the alignment is off I doubt if you will ever wear out a set of trailer tires. You will always run out of time before you run out of tread..

I just had my China Bombs replaced on my new Blue Ridge. I would rather pay $480 for new LT tires than take the chance of having an eight foot hole in the side of my new trailer. Les Schwab here on the west coast sell a great Lt tire made by Cooper Tire. May not be perfect but I feel a lo tbetter when I am forced to go over 65

What's the load rating and sidewall strength?

Goodyear has an RV tire care and guide. Halfway thru the guide are tables for tire sizes, weights and pressures based on weight. Not sure how well that would apply to your tires.
