Just got new tires on my truck today, Duratracs in 265/70R17E (121Q). As I was driving back to my house I noticed that the guys at the shop had inflated these new E-range tires to 39 in the front and 38 in the back, same as the stock, P-rated (115T) Fortitudes I had.

That can't be right...is it? I've heard people recommending 50 or even higher for E-range.

Also they said an alignment was recommended...then as I'm driving back I notice that the "center" point of the steering is now to the right of center... what good is an alignment if it creates problems where there were none?

Tomorrow I'll probably take the truck to my dealer instead and have them give an opinion, and hopefully look at the steering problem. First time I've had Canadian Tire touch any vehicle of mine and probably will be the last time. From this and all my past experiences with their customer service, they deserve their 3-star rating on google reviews as far as I'm concerned.

That said, the tires are quieter than I expected.

 

I run 45 frt, 40 rr with my load range E tires no load.
.

 

Here, the tire shops will put exactly what the DOT sticker says, to cover their butts.
BTW, always check them cold.

 

You should make them fix the alignment. I would have turned around.

 

The alignment problem is just pure laziness on the techs part. Steering wheel should be dead nuts center when they're done. The wheels might be aligned, but by jacking things around, many times the steering wheel gets out of adjustment. I had the same thing happen a couple times on big trucks. Just laziness and lack of attention to details. Every single time I've replaced tires at places like Belle Tire, Discount Tire, they've told me my alignment is out, before the truck is even moved inside, and offer me their "free" check. I always decline, and still miraculously, I don't have weird wear or problems.
When someone tells me they can tell my alignment is out from a 100' away, I get suspicious.
Canadian Tire doesn't exactly hire the cream of the crop with a built in alignment machine for a brain.
The dealer isn't always the best either, but your chances are much better there.
FWIW, I'm running Raptor wheels and Raptor size tires, 315/70/17 LRE. According to the door sticker on a Raptor, I need 44psi all the way around, that's hat I run, and no odd wear.

 

I run 40psi all around with no load. If I add too much more (with no load) they are like driving on super ***** bouncing all over.
This is with BFG KO2's E rated 285-65-20.

It's up to you to experiment a bit and find your comfort and "wear" zone. Increasing the load generally requires increasing the tire pressure. Check max pressure on the actual tire and air accordingly. 75-80% of max is a good place to start.

 

Agree. Last time I even had alignment checked was well over ten years ago. They said it needed alignment, that it was "X" out. I drove away, saw wheel was off, and drove back. They fixed the wheel and said it was "X" out. So I said, you moved it X, then moved it back, so it never was out. I want my money back. They gave it to me, and I drove away. I have never checked alignment since across all my vehicles, I watch tire wear.

 

Same thing I do, unless I've lifted/lowered the thing, then usually the alignment isn't off much, but in those cases, it's good insurance.

 

The steering should not be in the dead center when you're on the roads... It should be a little at the left or a little at the right, depending on what side of the road you are.

It should be straight on a perfectly flat surface, I agree, but it's not the case on our roads. They all have a cross slope to evacuate water, which explains the slight deviation of the steering.

The steering on my brand new 2017 is a little on the left most of the time... And sometimes a little on the right (when I'm in the left lane of a highway).

 

Ya, the crown of the road may be regional, and local. Most roads I've been on in 48 states and 3 provinces, have been pretty much close to level, notice the word "most" and "close", at least enough that the wheel won't be cranked too much one way or the other. It would seem most people, if they pay any attention at all, and it looks like the OP does, would know when the wheel ain't right. I don't know where in Ca you are, but I doubt if your roads are any different there, than anywhere else in NA. Unless you're up by James Bay, and then all bets are off.
