That's what I've been told by 2 wheel companies when trying to buy a certain wheel for my '84 2WD. So..looks like I'll go to 16X8 instead of stock 15X7. I can get correct pattern/backspace on 16's. What would be the best tire size for the 16s ? This is just a driver truck..thanks..j.

 

Jer - I'd go to Tire Rack and look at tires by size and select your current size. Pick several, like maybe 4, and hit "compare". That'll bring up a page with specs, and note the rolling diameter of them. Then go tell it you want 16's and pick a size. Pick several and compare, and then adjust size up/down to get the same rolling diameter.

Also, they have a section where you can chose another wheel and tire for your vehicle. Do 16's and I think it may tell you what size you should have.

 

You think 15" is hard to get tires for try 14" for my other project!
I just hate having to get new wheels as I like the old school wheels I have on my projects now as they are time period correct what they are on.

I ordered my 15x10s through Jegs and CooperCobras online and absolutely love them.

 

What tire did you run or wanted to run on the 15 inch rims? They have a thing called "plus sizing" when you go to a larger rim.

For instance if you were running 235 75 15 inch tires before, you can also run a 235 70 16 and be very close to the same diameter and tread width as the 15 inch tire.

235 is the tread width in mm. 75 is the height of the sidewall, which is a precentage of the tread width. So with a 235 75 15, the sidewall is 75% of 235mm. So if you go to a 70 series tire, the sidewall is only 70% of the tread width, which works out well with a larger diameter rim.

 

What "certain wheel" are you trying to get?
What lug pattern and back spacing do you need?

I want the "salt flats" style..At first they said they would do 5x5.5 and 4 1/2 BS..THEN..he emailed that the 5x5.5 can't be done on that wheel ??

 

As always..I appreciate the help..j.

 

So, your ideal is the VN470's?

Knock off center caps, or no...

 

Those..or the Rocket...33..style. Not sure which cap..j.
