hey, i'm looking at putting larger tires on my 4runner. Currently running 235/75/15s which works out to a 28/9.5/15. Wanting to go slightly larger to a 31/10.5/15 but i am questioning clearance issues. Has anyone put 31s on a stock 2nd gen or are the spacers needed. The spacers give 2" of lift in the rear, and if needed i can do the 1.5" lift in front aswell. I dont do tonnes of off roading so i'm not particularly keen on dumping 5-600 on a full lift when the mass of my driving will be highway. Also would i need to extend rear brake lines or anything like that? thanks for all info
