Tire Size Fitment Master Thread

[9zero1790]

Something to think about: the top of the tire does not flex. If its not touching the spindle now, it won't touch the spindle ever...

oh thats some good news! thank you! So am i reading right yall needed spacers and wheels?? or just a combo to equal 0 - +1?? some days i miss having a bigger truck. if i could afford the tire it would fit lol.

I run 285/70r17, I don't think I needed a spacer to fit. I put them on when I had skinnier 255/80r17s so they would sit farther out. I never took them off. With the 1" spacer and +55, I am sitting closer to +35 offset. I was able to fit 285/70r17 on a completely stock truck, only kissing the crash bars.

@AndyMedic had to show me up and get dope wheels.

I like that the wheels sit flush with the fenders on my truck. I've beat my wheels to crap, so they will get replaced eventually.

I have a picture somewhere on this forum of my order and tires. I can take a picture if wanted tomorrow also. Mine are a touch past the fender wall.

Mark, it’s important to have a little bit more info just so you know exactly what you might be in for. Particularly as it relates to crash bars.

@Colo_Ranger - I see you have no front crash bars - were the rear bars also removed, cut, replaced with aftermarket?

@AndyMedic - what’s your crash bar situation - removed, cut, aftermarket?

Mark already rubs at full lock and if he throws on a spacer or goes with a lower offset wheel to provide some back space, that rubbing could get worse. Did you guys experience the same? How did you remedy it?

This. If it's not rubbing now, it won't rub later.

To bring it to the same clearance as factory, you need a half inch spacer or a wheel with +40mm offset. Factory is +55mm.

Your Tiresize.com report shows a 255 factory tire going to 285, but the factory tire is 265, so it's 20mm up-sizing to go 285, not 25mm.

A 10mm (3/8") spacer, or +45 off set rim will put the 285 tire, back to the same space from the spindle as factory. I know it's not a big difference, just pointing out the 255 type-o.

Hey Jay, how’s it going?

I pulled that number from my window sticker. Maybe our tires differ by model year or trim level. ?‍

Pics or it didn’t happen, right?

Hey Duke, my apologies. I thought all Rangers came on 265s.

Maybe it’s a Lariat or an FX4 thing - I thought they all came on 255s. ?

I'm running a 285/70 r17 8.5 with 0 offset. 2 inch level kit for tremor.

That looks perfect

that does look nice! Can you get to full flex and compression without binding or rubbing?

Thanks Duke! So, the ready lift high clearance bars are going in as we speak. also having the right rear brake fixed - again lol. I figured if it was already going to the shop id let the pros put up with removing the stock bars.

so when I get the truck back it will have the 2.5 lift all around from the Bilsteins and leaf pack, the ready lift high clearance crash bars and stock sport 17 wheels. the tires i put on are 285 70 17 Cooper Evolution M/T. I think part of my issue is that the Coopers run big. most 285 70 17 are like 32.4 - 32.6. The Coopers are almost dead on 33 at 32.97.
The tires rub at full hard left and right turn without compression or flex. The sport wheels and new tires do clear the suspension parts / spindle but its very close. a number two pencil can just slide between. barely.
So i feel like i need the tires to move out to toward the fender. however, like you said i dont want that to make a new issue lol.

I’m glad those bars are going in. It seems folks think you’re good with your spindle clearance but some small spacers or a set of +30mm or so offset wheels will solve that.

See how we spend your money here, huh? Your speedo will be off by about 5-6%. When your speedo reads 57, you’ll be doing about 60. Your truck will also calculate your gas mileage incorrectly. It will calculate worse than reality. You can fix it in Forscan (I don’t know how) or with some tunes.

Post pics.
