Gotcha, I just realized that you put it in other builds. I thought it was going to be more off road.
I have a Sami and a 3rd Gen runner, so I totally get the positivesnand negatives of each.
Like I said, I really like the idea, I had kinda a similar idea for a cheap, light, go fastish build. I was thinking of running 37s though. With rcv's in the front an being lightweight, I'd bet it would hold up well.
Aren't 235/85s mostly going to be 10 ply tires?
If that's what you're after, get some 33x10.5 At's. With how light it will be, I'd really try to avoid 10 ply tires, as they will make it ride shitty. 15s will fit with different rotors and calipers. They came stock on many tacomas and 3rd Gen 4runners. They will literally ask you when you buy brakes if it has 15s or 16s.
There is also 255/85r16s, but I'd bet they are all going to be 10 ply too.
