tire option for the FJ Cruiser TRD Wheels

Just ordered a set of the Anthricite TRD Wheels and was wanting to know if I can use the stock tires on them atleast until they are wore out? The tires I have are BFG Rugged Trail 265/70 R16 and they recommend using 265/75 R16. The problem is, I don't want to spend $800.00 on a new set of tires when I only have less than 8k miles on the set I have and I have the Toyota warranty that will give me x amount of dollars after x amount of miles as long as I rotate at every oil change. Any help on this would be greatly appreciated..

 

You should be fine. Here is some info with an EXAMPLE explaining. Hope this helps. Your 70 series will be a fraction of an inch shorter sidewall height than the 75 series. No biggie. P225/50R16 91S
The 50 indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43". If this tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall.

Thanks for the help, I was hoping I would get that response. Forums like this make life easier for guys like me with minimal mechanical know how.

By the way, I got a great deal on these wheels from a dealer in California @ $500 for a set of 4 and $79 dollars for shipping. you can contact him @ sedwards@frankmotors.com
I think he said he recieved a large order of them today and mine will be here within te next three days.. I have listed the particulars below if anyone is interested..

Yeah a lot of us got in on that deal. I think with a medium lift (2.5" - 3") you can run 285's with those wheels b/c of the 4.5" backspacing.
