Another tire question

No, because a Load Range H inflated to Load Range E (or whatever) inflation pressure behaves like a LR E (or whatever).

You might want to consider WHY you have a LR H on the vehicle. A bit more information would be helpful, like:

• Year, make, and model of vehicle
• What does the vehicle tire placard says about size, Load Range, and inflation pressure?
• Did you weigh it? What did you get?
• Make and model of tire
• What inflation pressure are you using now? How did you determine that?

There is an E speed rating, but in this case, it's referring to the Load Range. It's a way of designating how much load a tire can carry: For the same size, a LR E will carry more load than a LR D (albeit at a higher inflation pressure.)

The old way of doing this was "Ply Rating" and the old 10PR = LR E - BUT - that confused many people into thinking that 10 PR actually had 10 plies! Not true, as a typical LR E tire uses 4 plies - 2 polyester body plies and 2 steel belts.

The weight, sidewall stiffness. and RR of a LR E is only slightly worse than a LR D - and that's because LR D tires also have - typically - 2 polyester body plies and 2 steel belts, just a bit stronger.

That means you shouldn't worry about using a LR E in place of a LR D - the differences are minor.

Do you really need E tires? Extra capacity is nice but don’t go overboard. I wouldn’t be comfortable with an inexperienced salesperson.

E tires are usually 10-ply and used for heavy vehicles like RV or big trucks or 3/4 or 1 ton pick up trucks that will carry heavy. Often they are 80 psi tires. Their speed rating should be much higher than you ever want to drive a trailer or RV.

I forgot what vehicle this is for.
A problem getting E tire for a vehicle that does not require E is that the sidewalls are very stiff, so for a light vehicle or trailer the ride quality will be more harsh. On trailers the tires are a big part of the suspension spring so you need the correct tire, usually a C, so the tire will flex as part of the suspension and give a softer ride.

E tires will also be much more heavy and thus cost you more at the gas pump.

Since there’s a bunch of sarcastic responses... E is a generic category of load rating. In the light truck tire range.
Don’t worry about speed rating for any LT tire that you’d put on your RV.

E is a code for the number of plys in the sidewall, and affects the weight rating.

Ahh thanks!

I have not purchased yet, but am about to. Idiot salesman was no help so i panic posted here.

Thx again

what kind of tires did you buy? what does the side say?

E is a code for the number of plys in the sidewall, and affects the weight rating.

So is the E when it's going to fall apart?

E is first letter of Endurance!:S
