Tire/wheel size...jeeeze!

Jeeze,
Info overload.
There has got to be a better way to figure out what will work.
I'm a newbie at tire size, I've searched the forum and gone to the links.
I'm pullin my hair out here.
I'm adding the 2.5" leveling kit and have to do the front end toe-in adjust anyway.

My tires are ready for change so I figure I'll do it all at the same time.
I have the stock 18x7.5J rims.
It has 275/65-R18 which I suspect have been on it since it was born.
What'll fit, 33s, 35s..... width.....offset..... I'm diein' here.

I don't mind studying what to do but it seems all the links give you just
enough info to confuse the issue or it requires more info than I have without buying a caliper.

In short, what are y'all using that works with what I got?

Thanks

I can still remember all the hours upon hours of researching, tire size, wheel size, lift or no lift, offset and all that other good stuff. I have an odd setup I did not want the tires sticking out to far.



2.5 AS, 325/60R18 Pro Comp X AT's, on +30 offset Moto Metal 951's. Little bit of rub on the mudflap but nothing horrible. I do not think I will go this wide again though the truck is kind of squirrely for the type of driving I do. Hope this helps a little.

Here's a good rule-of-thumb.

If you're staying with stock wheels you can safely go up two size. You got 275's so you can usually go up to 295; safely. However, you see the guys here that run 305's on stock wheels. Now, that's fine but a safe rule-of-thumb is 2 sizes. The tire brand & size you choose will usually tell you what width rim it should go on.

As far as rim offset...well that depends on the "look" you're going for. If you want the "sticking-out-the-wheel-well" look or if you want the stock tucked in look or even with the wheel wells...each wheel will have a different offset depending on the look.

What are you going for?

I'm not ready for new wheels yet so I suppose the offset is what it is.

I'd like to put as big a tire on it as I can staying with the stock 18x7.5 rims.
I just dont want it to rub and I dont want to have cut away anything.

I didnt realize the tires had what rim they would fit.
I suppose I'll stick with 2 sizes like you said unless the 35s say they'll fit that rim.

I am running 305/60R18 on the stock FX4 rim. I just got them installed yesterday. I have a 2" leveling kit. The tires fit perfectly on the truck and ride great.
