Topic: tire size on my runner

[OFFRODN]

Ive got a 1985 4runner with rears up front and Chevy's out back allpro hysteer ifs steering box billsteins trail gear hoops marlin fj80 master cyl.  steelbraided brake lines vented rotors red top optima batt. 1.5" wheel spacers and some 33x12.50's and locked front and rear my question is I'm wantint to know if you guys know if i should run 39.5" or 37" bias ply tires IROK'S   I forgot to mention i already have 5.29's and  cut out fender wells

That Optima battery is gonna pevent you from running anything over a 33" tire.....   haha   Im just messin around,  you forgot to mention what gears you are running, since that is the most crucial part espacially if you wanna run big rubbers.

I just ask myself "Self?  Will you wish you had got those shiny 39.5's instead of the 37"s in six months or less time?"  Most wheelers develop a nasty case of Big tire envy.  I run 35's  and wish I had 37's, SO I just lowered my truck to make the 35's look meaner!

Iroks kick arse though.

X2 4ds is where its at! I bought 36x13.5 irocks and now I wish I had 40s although the 36s are plenty. For an all around tire anything from a 35 to a 37 will get you in more jams than you could hope for, while keeping breakage to a minimum. (with longs of course)

Definatly would be cool to get the 40s but if you arnt looking to upgrade gearing I would stick with the 37s,  tires dont do any good if you cant spin them.  The other question you should ask is how tall do you want your rig and how much fender triming do you want to do.  Im not a yota guy but i think they dont fit 40s unless your going to do some rimming or your gonna go sky high.

youll rub the 39s unless you link it or have crazy bump stops.
i cut out 2"in the back of the front fenders and took out as much as i could of the fire wall and im about 1/2" from rubbing with 37x14.5
