I just got onto days off from work - after dumping equipment and before leaving the shop, my area manager mentioned that the Toyo M-55's are now available in 17" size(s). There was no mention on how many different sizes however.

We've put the M-55's on our company trucks in the past when they had 16" rims, but were unavailable when Ford went to 17". They are an incredidble tire IMHO. While the M-55's were unavailable, we switched to Cooper Discoverer ST's on the 2005 trucks (they're E rated). I've got 5000 km on mine currently - had them rotated yesterday while truck was in for service - still look new, but I heard some comments from others that they're not wearing as well as the Toyo M-55's. More mileage on them help me form my own opinion on the Coopers.

 

why do you have to have an e rating? the d rated 315 will hold the same amount of weight, more in some cases.

 

I don't know about everyone else but the last thing I want on my truck is a 315 tire.

 

I have heard people complain about sidewall flexing in the past, but i think if you are concerned with that notion then you should have strongly considered buying a DRW instead of a SRW.

 

I just don't want a big tire.

While I'm sure I'll probably just go with a D-Rated all terrain, if I can find an E-rated one. I'll be there.

 

yeah i always seem to go with the biggest that will fit stock, but you do loose a little MPG. I did not notice very much power loss at all though.
I was going to go back with a 285 (instead of another set of 315) but i would have to change out my spare and pay $ to have my speedo changed again.

 

They just don't seem that big anymore

 

Looks nice. I cant belive almost a 35" tire will fit stock

 

I wish the tire makers would make 75, 80, or 85 series tires that would fit our 17in rims and be available in E ratings. That way we could go with a taller but not wider tire.

DING ! The Ghost of Diesel Present has granted your wish :^)

Michelin seems to be offering a 235/80 17 in a load range E, in their LTX M&S tire. The ST steel rims will work with it but the aluminum wheels won't. IT looks like a dually tire.

 

What did they run you? I am told that they are expensive. I called the Toyo dealer here and his price was more than $1005.00 and that was the AT, he said the MT would be more and have to special order them.

 

I paid just over $1300.00 for the 4 tires, and $150.00 for the mounting and road force balance. Before you panic remember thats in Canadian Pesos. The tread is more aggressive than I wanted, but I need the load capacity. Had good timing too, the next day we got 6" of snow.

 

Tweeter, what size and tire did you end up with. I'm running 4 265 70 17 and 2 235 80 17 on my dually, all Cooper s/t. Price varies alot here. I got them at my local country garage for $295 cdn installed and ballanced. (not studded) So far they are the best wearing tire. I got 60k km on them so far and they are at 13 tread depth starting at 19. I'll ridem till the carcass scream just like the originals. Kerry

 

a 235-80-17 and a 265-70-17 have the same overall diameter.

 

Drew03, Yep they are within .1 of an inch when new. I have them both on my Duals. The tire I would like to have and I think they would sell a ton would be the 255 85 17... That would be a 34 inch tire 10.25 wide. No rubs even offroading without a lift and great in snow and mud. ks
