85 2WD max tire size

[DandysRanger]

Bought some nice looking stock 15" ranger wheels. They came off a lifted 4 x 4 and have 30" tires. Any chance these will fit our '85 2WD with leveling springs? I'm thinking not so what should be the max size I should consider? I have been looking at 215/70-15s.
TIA,
Jim

I put the 15 inch B-II wheels on my ranger with no problems except the speedo will get you in trouble if your not careful. I put a 3.73 ls carrier in the rear and with a tan speedo gear my speedometer is spot on. If you keep your gear ratio the same a black speedometer gear will get you close.

Sorry it depends on your motor and transmission bigger tires equal less power unless you change gear ratio/s. Depending on your tranny type count the teeth on the speedometer gear if your driving faster than your speedometer says you need a smaller gear in the tranny.

Thanks Kimcrwbr1, What size tires did you end up going with? Are your wheels 15"? 2WD lift or no lift?
I anticipated some trouble with the speedo but I've dealt with that before on all my vehicles.

215-75R-15 with stock suspension with plenty of clearance

With the taller tires I could see a problem with clearance but I dont go wheelin but with the 2.8 I didnt see much power loss with the 15 inch wheels.

Thanks kimcrwbr, That is what I was looking for. I think I will try to fit what I already have. If I need to buy some new rubber than so be it...
You have a nice looking Ranger.

Here she is with the new sneaks. 30" tires on 15" ranger wheels. No lift just 1 1/2" leveling coils. Could use another inch or so...

You say 30 inch... are they 30x9.50r15, or are they a metric size very close to 30?

I ran 31s on my stock Bronco II, but they rubbed really bad on the front sway bar (So I removed it... But its a trail rig, not a driver.)

 

[DandysRanger]

yep. 30x9.5x15. No problems with rubbing but it is 100% street.

You do have leveling springs, my b2 was pretty saggy before it headed for the junkyard on the stock springs. Looks good.
