E rated tires

CarCrazy49 · April 18, 2020

Should I stay away from E rated tires on my truck? I have a 20 Denali crew cab with the 6.2. I’m in northern CA so roads and weather are not a big deal. Truck will see some towing but nothing crazy. I’d like a tire that is good for Tahoe snow next year. Problem is I have 22” wheels, the stock Bridgestone tires suck and there are very limited options for replacement. Sticking with a highway tire I can stay in the stock size with a Michelin but I’d prefer an AT tire. For AT’s I can go 285 50r22 with Nitto terra or ridge grapplers but they are E rated tires. They also have a XL 305 45r22 but that may not fit on the stock wheel. Frustrated with the lack of options. I emailed Nitto earlier this week and they said there were no plans to make their AT tires in our stock 22” size.

Question is, if I go with the E rated 285, is it going to kill my mileage or make the ride too stiff? Any other alternatives out there?

E load tires will make a dent in for mileage and will also ride firmer.

I would avoid an E-rated tire.

The 305/45/22 is only 1.2% different than a 285/50/22.

We are talking a 33.2 to a 32.8in tall tire and 11.2 to a 12.0in width on the tire. The 305 is shorter but slightly wider.

E rated tires aren’t that bad... I drive on quartz rock a lot so I need the greater cut resistance. Got tired of replacing tires...

Yeah, I think the 305 45 22 makes the most sense, as long as they don’t rub.

I am looking for a snow rated 22” A/T P-rated tire as well. Pay attention to tire weight as sometimes going up just 1 size makes a huge difference. Most are XL rated to if that is needed.

This is close but no 3 peak mountain snowflake and probably the one I will choose due to ride quality, on-road performance (where wife will spend most time) and A heat rating. We have my truck for more aggressive off-road needs

Here are snow rated a/t from tirerack.

the Cooper is for some reason left out after applying filters but here is the link

Any concern about going down in size going that route? The sidewall is already so small on these 22’s. The stock 275 50 22 is a 32.8 tire, 285 45 22 is 32.1.

Sorry. This is for wife’s Yukon. I would keep the OEM size or +1 as long as weight is not much more and not E rated (just my opinion as the extra cost for speedometer calibration is not worth it for the comparatively small extra size). 1/3” sidewall may not be enough to change anything and in the link by Druder he says he is happy with them on his 1500. E rated on the 2500 is what it is designed for so XL is high as I would go for a daily driven 1500 on pavement. No options in the A/T area for 275/50/22 size...that I can find. But the 305/45/22 would be a good choice to like CarCrazy said...but not a lot of options.

Here was a pic from an experiment with my Stock size AT4 tires on her Yukon.

I live in the middle Western part of Oregon. I settled on an E-Rated, snowflake-rated tire from Les Schwab. I went from a 265/65R18 to an LT 275/65R18. I have done that on two different 1500s, a 2018 with a 5.3/3.73 gears and my new 2020 with a 6.2/3.42 gears. I didn't notice any change in ride harshness or fuel mileage on the 2018, though that tire did make the truck more stable. I just got my 2020 and just put on the tires and while I don't have any fuel mileage comparison, the ride isn't any more harsh but the truck handles a little better. I am running these tires at 35 PSI.

The difference in weight between the car tires the truck came with and the Es is 18 lbs (35 vs 53). When I was looking I did find a C-Rated tire but it was only three pounds lighter and that is probably why there aren't many Cs and Ds anymore.

I am not sure if an E-Rated 22" tire would be a similar deal. There is less sidewall so I don't know if it would make it noticeably harsher. I doubt there will be much of an effect on fuel mileage if the tire is the same size and you are just going from car tires to an E. However, if the new tire is significantly taller and wider it will affect mileage, sometimes significantly.

I have E rated LT 35” Nitto Ridge Grappler tires on my 20 HC and I have no issues at all. They might ride a little firmer but the truck is still smooth and I love the look!

I have never had issues with E rated tires. The ride is sometimes just a tad stiffer, but not by much, and the handling has always improved by a greater margin. I usually get much better longevity from an E rated tire as well.
