I have no idea about them specs? I do know that there is not much clearance between the tire and control arms. Are you familiar with TacomaWorld.com? There is a lot of info on that forum, jump over there and be prepared to read quite a bit. I am a member over there under the same name also btw. I got my specs from reading on there and seemed to be right.
If you want to look for reference, look in my garage. I've had no clearance issue with my specs and I did have the same tire and wheel combo before leveling the front end. Tires are the stock 16" size of 265/70/16 which should be the equivalent of the stock 17's.
Good luck!
