I've been searching and reading for days. I understand backspace and offset. I also understand that one size does not fit all. This should be easy for those in the know. I think I know - but, my decision is a thou or a couple+, so I'm asking. I acknowledge the experience and expertise here, any advice is appreciated. I'm Erik, dad who is setting up his son's first car, 05' 4R Sport, I have an 05' Tundra Double. Both 2WD

A thousand because my 05 Tundra needs new tires. Easy, buy them.

But, my wheels are beat a bit, so an improvement would be nice.

The kid's truck has new tires, which happen to be the ones I use. And, a more aggressive tire would be nice on his 4R. His wheels are clean, and shop blackout paint.

In a perfect world, I would just bolt his wheels on my truck and buy him new. We both have 265/65/r17, and like it that way.

His offset is 30mm (17X7.5)

My offset is 15mm (17X7.5)

I don't really want to increase my offset with a bolt on of his wheels, I doubt it would create an issue, other than a more narrow stance - slight, but the wrong direction. Spacers are out.

TRD wheels (4mm offset) want a 265/70/r17 or better; 17X7 wheel. /65's/ want 7.5" or wider.

Here's my question. Clean the wheels the best I can on the Tundra, and buy tires. OR....

Buy 17X8 TRD knockoffs with 5-15mm offset (I think they are 15) for one or both trucks, get him the KO2's or something similar, and I take his tires?

The real question, is - 17X8, 5-15mm offset, with 2.5" lifts on both trucks, stock tires at 265/65/r17, is there any possible way I can go wrong with fit?

Thanks for reading. EA

So, I'll answer my own question. Know the offset and backspace of your OEM wheel - google. Search forums for tire fit for your stock or lift set-up, model and year. Use a good offset/backspace wheel calculator found online - google. Check tire/wheel sizes - google. Look at pictures of other's set-ups with your ideas in mind. I did all of that and knew with confidence that OEM 17X7.5, 15mm offset, I could go 17X8.5 0mm offset, and with stock tires (265/65/17), I would be 2mm less backspace and 1.1 inches wider stance. No problem. I also knew that when my tire guy did not have the 265/65/17 or the 265/70/17, that I could still take the 275/70/17. And, I also knew the wider tire (10mm more) had a better bead grab. This ended up on a leveled Gen 1 Tundra, 2WD, leveled (2.5" front lift), but the principals apply to all trucks. I left the 4runner with stock. Although, the 4runner is stock, my Tundra looks sic and no rub, and I'm not suprised. I knew it would be the case on the fly because I knew the math and the forum reports. So, thank you for posting your experiences.

You can see these pics for a while, they just prove math and research are the way to go, there are no short cuts.
