Tire Height vs Measurements-Best Bargain 34" tire?
So when I have questions, I ignore Buddha's ramblings and go straight to the source for all things wise: Sigforumites.

That said, I want to know from the tire knowitalls how to determine the least costly way to purchase tires of a given height. I know some tires are less common iterations, but some are cheap just because that's what everyone makes and sells.

I'm specifically looking for a 34" tall tire, 18" OEM GM wheel. I could live with a tire that is a "tall" 33, but 34" is the goal. Which measurement is going to be my most cost efficient option to get to that height and not cost me my firstborn Sig? If 2 options are the same, I'd prefer the one that is going to least interfere with mpg, even though that's a relative request (maybe I've read that tall skinnies are more fuel efficent?).

So, can someone with tire knowledge point me in the correct direction?

Tried this little calculator?

https://tiresize.com/height-calculator/
You're starting in the 295/70R18 range(34.3" height).
It also gives you actual tire recommendations.

You will need to account for recommended vehicle inflation pressure and load/weight of vehicle, but that link is pretty damn accurate.

You can also search by tire height:

IRT to mileage, less aggressive tread, narrower passenger/touring tires will generally yield better mileage than off road/all terrain style tires. They also run quieter.

Best mileage is probably this guy right here(Michelin Defender LTX/MS), cheap is relative though... Wink :

In short, good luck...

While there are standard ways to measure tires, it doesn't mean that the manufacturers are honest in their measurements. Throw in rim width, air pressure and what not and you'll get even more variation in height. Plenty of people have posted real world measurements on forums, but then again they are subjective and subject to various variables.

A LT285/75R18 tire is listed around 34.8" so it should be all of 34" and than some. This size will also work well with factory 8" rim if that is what you have? MPG will most likely take a hit from factory tires.

Thanks guys! I'd seen the tire size calculator, but when I went back and looked there was an additional tab there that I hadn't seen that will give you a list of all possible options when you input the size. In my case, I just took pics of those screens and searched each size to see what the least expensive options were.

Again, thank you all for your input! Helped a ton!

LT275/70r18

33.4" and the right width for OEM wheels, not too wide for poor fit.

That is a KILLER price for that size tire, and I've been reading over on the ih8mud forums that the Falkens have been getting good reviews. Gracias.
