What is the stock wheel size for my car?

 

Stock size is posted on the drivers door jam as well as recommended tire pressure, it is this way for exery car and truck sold in the US.

235/70/R16 is stock size.
You can go 245/75R16 but no bigger without more than a 3" lift.

 

wheels are 16" by like 7 or 7.5 inches and your lug pattern is 5 on 6.5...

 

So these wheels wont work on my LR?

Do you have alloy wheels? If so they are 16x7. Why replace your factory wheels with internal bead locks with fake external bead locks? If you're really intending to off road your truck you want the bead locks so you can air down without worrying about the tire coming off the rim.

Those wheels will work if they have 5x6.5 bolt pattern available. It is a unique bolt pattern that not many aftermarket wheels are available in. You can go down to a 15" wheel if you want to but anymore the better tire selection has moved to 16". When I was in high school and first getting into vehicles 16" rims had very few tires to chose from while pretty much any size was available for 15" rims. Now that has reversed.

I would go with either the 15x8 or 16x8 with enough offset to move the wheel and tire out a little to prevent rubbing. My 245/75 on factory rims rub on the trailing arms at full lock.

 

I highly doubt those wheels will fit on a Disco. The bolt pattern will never fit.

Get yourself some NATO steelies, they're cheaper and they'll do you way more good, not to mention they're actually designed for LRs.

 

One of the pieces missing for most people is that for most applications, a narrower tire with a more aggressive pattern will out-perform a wider tire...

When you look close at the oversized "Super Swamper" type tires, you find a notation that says "floatation sizes". That means that the tire is *supposed* to be big enough that for the weight of the vehicle, it will provide a floatation effect on mud, sand, etc. Put simply, they decrease the pounds per square inch of tire contact patch.

Problem is, that's for 3500lb-ish *JEEPS*. When you get to things the size of Discos, you need much, much, much wider tires to provide the same function.

Can't tell you how many times I had to pull Rover newbies out of the muck and sand with my Defender on account of them getting oversized tires which were too wide to give them enough pounds-per-square-inch to get "bite" on the surface, but at the same time weren't wide enough to "float"...

In winter, you're better going down a size, to 225/75 for even more "bite".
