Compatibility of Load Range E Tires To Replace Load Range D Tires

Question

Question:

I just bought a 2008 Brookside by Sunnybrook 349FWSB. I need to replace the 10 year old 15” tires. The wheels say max load is 2600 lbs and the tires are D load rated with 65 lbs of pressure. Can I put E rated tires on these wheels and do I even want to?

Helpful Expert Reply:

You absolutely can move up to Load Range E tires for your replacements on your 2008 Brookside by Sunnybrook. Moving up one load range won't drastically impact the ride and make it too firm, but we don't recommend jumping multiple load range levels for that reason.

I recommend the Provider ST225/75R15 Radial Trailer Tire # TR225LRE which is rated for 2,830 lbs at 80 psi. It will have a higher ply rating so it will have a more durable sidewall construction. It is rated for speeds up to 81 mph and has a 2 year warranty.

If you want a better warranty on the tires, then I recommend the Westlake ST225/75R15 Radial Trailer Tire - Load Range E # LHWL304 which is rated for 2,830 lbs at 80 psi and speeds up to 75 mph. It comes with a 5 year warranty and two years of complimentary roadside assistance.

Good news, I can help you find a tire for your Sundown Horse Trailer. The 205/90-15 is a close tire size to the 7.00-15. The closest size to a 7.00x15 tire that we offer would be a 225/75-15. One 225/75-15 tire that could work for you is the Kenda…

I have a couple of options that will give you more ground clearance depending on how your 2012 Lance travel trailer is set up. First, if the trailer uses double-eye leaf spring suspension AND the axles are on top of the leaf spring stack, AND if you…

In your situation changing to a higher load range tire will not affect the odds of a puncture (since the ply rating does not actually refer to layers of material in the tire but rather its strength). Moving to a higher load range DOES offer the…

I have attached a chart you can check out that describes the torque needed per wheel size, wheel stud size and material. For an 8-inch wheel with a 1/2-inch wheel stud the torque is 75 to 86 ft-lbs. For a 15 inch steel wheel with 1/2 inch wheel studs…

All things being equal, including price, I'd go with the higher rated tire when available. Even if it's not really needed you end up with a tire that's made a bit stronger. The biggest difference you'll notice is that you'll have…

Answer 8

That's actually not uncommon for your tire's rating to be less than the trailer's GVWR since you have to keep in mind that approximately 20 percent of the trailer's weight will be on the hitch. With that being said if you'd feel…

Answer 9

The advantage you get from going to a higher tire Load Range is increased weight capacity for the tires. If your current tires are adequate for the weight of your trailer you really wouldn't gain anything by going to a higher Load Range than…

I completely get where you're coming from but the only time we ever say mix-matching tire sizes or even ply ratings is acceptable is in an emergency situation where you need to hobble to the nearest trailer shop for a repair. Aside from that…

Answer 11

Going to a tire with a higher rated load range will mean you will need a higher psi rating. The problem with going to a higher rated tire is that it may result in a stiffer ride. For example, a Load Range E tire like part #TR225LRE is rated for a…

A tire of size 215/75-14 can be mounted to a 14-inch wheel with width of 5-1/2, 6, 6-1/2 or 7-inches. A narrower 205/75-14 tire can mount to many of these same wheel widths: 5-1/2, 6 or 6-1/2-inches. Moving to a higher load-range rating will give you…
