Just finished adding in a 3 inch body lift and 2 inch shackles on my 86 runner. Looking to get a set of 31's or 32's for it. Shes still got the stock gears and I don't want to swap em out just yet cuz I'm still wheeling an IFS front end. I'd rather save the regear for when I can swap to an SAS and install the lockers at the same time.

I'll deal with the "power loss" of the 31's but if I step em up to 32's is that gonna throw me way off?
My speedo is GPS so it won't throw the speedo off either way.

The truck is still used on road, and does do some weekend wheeling, so I'm willing to compromise.

Any one have any ideas as to how big I can go and still be streetable, and also what tire I should be looking into as far as both needs being fulfilled?

Ofcoarse I'd rather not spend a whole butt load of cash on em too, if I'm just going to buy 34's later when I SAS

 

31's I didn't find to be over-burdensome on a 22RE, even on the highway, from a power standpoint.

 

x2. I ran 31's for 2 years on my '93 single cab. I got about 20-24 hwy and no more than 17 city..usually around 15 with stock gearing.

 

Theres some guy on Yotatech running 34's on a bone stock no lift 86 runner. I tried PM'ing him, but he hasn't been on in the last few weeks. One of his posts said it was a daily driven truck and he's had no prob on the stock gears for over a year now.

I didn't think it was possible to even fit those in there without a lift, let alone turn with em.
If I could run 32's or 33's I'd be extremely happy as it would help out the diff clearance quite a bit, I even have the spacers to push them out for her already. Just not sure if I can do it so far, and I'd hate to throw on a set of 32's just to find out it does more harm then good while playing in the dirt.
