Will fourth-gen wheels fit a third generation truck?

[T.A.Kirk]

Looking at a set of wheels the seller describes as "fourth generation", and which are sized at:
-17x7.5
-6x139.7

I'm having a hell of a time figuring out if these will fit my '99 Limited with the Tundra brake swap on it. Can anyone with more of this knowledge at the tip of their fingers tell me if the backset is good on this set of wheels?

4th gen wheels are inset 1/2 inch compared with third gen so if you put wider tires on they will rub the uca. The 265's I had on cleared it though. Can't advise about clearing the tbu. That all depends on the spokes so need pictures or more info. Even then I think the only way to know us to try it. Or search the internet for pictures of the same wheel, and if they clear the tbu. There is a thread on this from way back which lists all the wheels that clear the tbu.

Thanks! I think I'm going to take a risk on these, because the price is good. If they don't fit, then I can sell 'em on to someone else who has a truck they'd work on.
