5th Gen Stock Tire Help

First off, I have searched and searched, and while there are many threads on 5th ten tires, I'm more confused then when I started. So I apologize, I hate people that don't search first, that is not the case here :)


I'm hoping I can get some help in what to look for in picking a tire. I have a stock SR5, and most likely will stay that way for the most part as it's a lease (maybe I'll buy it out but most likely get a 6th Gen ;) ). I just got a flat exploring FSR's yesterday, and it's time I get new rubber anyways as the stock tires are not going to do me any good in winter in Vancouver mountains (even just snowboard runs).

As far as I can tell I can bump up to 275's without any concern on rubbing. I'm still not clear if that's a benefit or not. I think I have to stay at 17", is that true? If I up to 18" does that help with ground clearance? These tires will be my daily commute ones as well, so nothing that wears too fast, I'd like to get 50K out of them. As mentioned, we live in a hilly area, traction on ice/snow is important.

My last vehicle (2wd Edge) I bought some great all seasons that were winter rated (Nokian WR2). But they did the trick in the winter, and the compound did not wear fast at all in the summer. No idea if those would be ok to bring off roaring. I'm not doing anything crazy, just want some protection for flat etc and a bit of mud/slush. Though it looks like they don't come in a large enough size

I'm also utterly lost on the side wall rating. I understand the concept of it, but can't figure out what # it is you're looking for in the tire listing.


Any help is appreciated. And again, I apologize, I know there's a lot of threads out there. If there's one that deals with what I'm asking, a link would be great.

thanks

275 is a little larger they the factory 265. Will you get a little more clearance, as aulen stated, read the Tire Tech Info, you will learn a lot. No, you can't use 18" tires on 17 inch wheels, which is what you have on the SR5. Remember reading about the 20 inch wheels that come with the LE? That is what they are talking about, the size of the wheel. As for "sidewall" strength, it is not a number, but a letter you are looking for. For example, the OEM tire is a P265/70R/17 The "P" is a 4 ply rated passenger tire.

I have Light Truck tire "D" rated, or D285/70/17. The "D" indicates it is an 8 ply tire. So, P 4 ply, C 6 ply, D 8 ply, E 10 ply......Be safe.
 
Just re-reading this - good lord, knew nothing.

Picking up Cooper A/T3's on Saturday. Went with standard 265's but now starting to wonder if I should have gone 275/285 (mainly for looks) - but don't think they come on 4ply anyways so even more expensive change.
