E rated tires needed?

[mschneid]

Picking up a 30' classic in a week and don't have E rated tires on my Tundra. Are they necessary?

[Sphere Guy]

mschneid,

It all depends on what tires you have now are rated. As long as your current tires can handle the load rating with your new Classic, you should be fine.

Just remember, you wheels or rims should have the proper load rating as well.

[mschneid]

I believe they are C load which I'm thinking aren't good. I'll have a 5hr drive after I pick it up. Should handle that I hope. Not going to be able to get new tires until after I pick it up. Will D rated work? I've had E and it's a rough ride in my Tundra 20" rims.

If the tires are in good condition, and if you have a good WD system for the hitch, the factory tires should do well. You shouldn't need 10 ply tires on your 1/2 ton pickup.

If your truck is rated to tow the weight, it should be rated with the factory tires. Check your owners manual and door tag. The factory equipped your truck to carry a certain load under a certain configuration, follow that, not what someone on an internet forum says. Toyota built your truck.

I put "E" rated Michelins on my Tundra for my 28' International. I drop the pressure to 50lbs when not towing and up to 75lbs when towing. I actually think it drives/handles better both with/without the airstream attached. However, I see you have 20" wheels, I have 18". My Tundra had a boaty feeling on turns before the "E" rated tires and now I like the handling much better. YMMV

Find your tires on this chart and inflate them per the load you will be carrying. Chart is good for all manufactures per Government standards.

I run Michelin Es on my truck and trailer. truck front axle 50lbs rear axle 55lbs. Trailer 45 lbs all around.

I am running the trailer a little high to carry the load if i have a flat.

In chart does not show tire ie b.c.d.e etc. or ply structure so IMO it is worthless info the way it is printed, or maybe I don't understand whether rating of b,c,d,e means anything. I would not put anything but E on my pu also same on AS big trucks another story as I go by side wall cap and run pressure as needed.

[HowieE]

You may what to revisit the chart. I see tires out to "H" listed depending on the size.

The ply rating is generally a function of the rating.

[mschneid]

This is what I have. I'm not a tire pro...

There have been many threads on Air Forums on tires. I have found some of the information to be laced with faulty opinion, esp as to trailer tires. There have been comments by one particular individual I believe calls himself "Tire Man" who is or was a long time engineer in tire manufacturing. As an engineer myself, I believe his information is excellent if you can find his comments. The best source otherwise is the tire manufacturer's web sites. Also, any good tire dealer should be able to give you the information you need.

I tow a 26' vintage A/S with a 1500 Silverado. I have LT load range C tires on the Chevy at 45 psi front and 50 psi rear. My trailer has 4 GYM ST load range D tires at 45psi. Been doing it for many years.

That said you can read the load rating on the side of your "C" tires at the max pressure. I think you will find them to be ok if you don't overload the TV and use a WD hitch.

[mschneid]

Thanks for the info gents!

Been towing my 30' over 4 years with original tires on my Tundra.
An upgrade might be nice, but it isn't necessary.

Not if you have a quality weight distribution hitch installed and adjusted properly. And don't overload the bed of the truck. When it's all set up and loaded for travel, take it to a CAT (truck) scale to ensure the truck's axles are not overloaded, GAWR for each axle will be printed on the driver's door sill. Check, but the factory tires should carry the axle weight when inflated to max pressure, or perhaps less as shown on the weight chart for the tires.

[larryglarson]

You do not need the heavy duty tires, the one that came with the Tundra will do fine, check the load rating on the side of the tires if you are worried. I do run 39 PSI when towing.

Good luck and have fun.

[m.hony]

39 psi doesn't cause the TPMS to alert?
I've been running 33 psi per the door placard.

No I have had no trouble running 39 PSI in my tires from the monitor, it can be reset to any preasure. I am not sure 39 is right, but my TV tires were running a little hotter than my trailer tires so I though I would try it, it helped and the ride in the TV was still good.

I also tow my 27 FB with a Toyota tundra, 18 in wheels. I put the "E" rated tires on last year because my previous factory tires started---chunking---. My Tundra towed the trailer just fine but once I went to the E rated tires, no more chunking ( meaning pieces of the tire were coming off in various places. I also inflate to 75 lbs when towing and drop the pressure to 50 lbs when not. Works great for me. Just FYI

My Tundra has 20" wheels and tires.
I might try the 39 psi.
I have never had any trouble at 33 psi, but anything to try and increase fuel economy...
I might also try 72 psi in the trailer tires instead of the 65 psi I have been running.
If anything else, this might cause less alerts from TPMS because when it gets cold the trailer tires will still be at 65 psi and the truck tires will still be at 33 psi.

It's really not difficult. You just have to do your homework.

First, what is your vehicle specs? Towing, tongue weight, payload limits? Second, what are you tire limits? How big are your wheels? How wide are your wheels?

Done.

You don't say what year your classic will be but, if it is a late model your tongue weight is about 60 pounds less (773) than my 25 (837).

I pull a 25 forward twin. I don't have E (10 ply), I don't have D (8 ply), I don't even have C (6 ply). Why? Because my wheels are so big, a Mud and Snow (4 ply) tire (M+S) gives me 2601 pounds limit per tire. That's 2 steel and 2 poly ply. All the info is STAMPED right on the tire.

If I went the whole way to E, it would give me 2757 pounds limit per tire. That's 156 pounds difference. Worth it? I think NOT!

I would have to get rid of my 20's which are 8 inches wide and go with a skinnier tire just to get the E rating and then . . . it would RIDE like a truck too.

Goodyear/Dunlop and RAM confirms.

Congrats on the 30!

Popeye
