Quick Tire Question

[Rocco83]

Will 30s fit with no lift? I need new tires and there are a brand new set of 30s down the road with rims and matching spare for $200. Much cheaper than the tire store.

[nickyg]

I think they might, If I'm not wrong I think stock tires are 28. You could always lean the tire up against your jeep to see what it looks like. or maybe make a cardboard cut out.

[Rocco83]

I think the regular tire size on it are supposed to be the 215-75R15. Which I believe is 27.7 or something stupid so I'm thinking the 30s would work.

I say go for it before it's gone! I think you'll be fine. Your speedometer might be a tad off, and you MIGHT experience a slight but of rubbing on full steer, but I say go for it.

Jeep will only be driven 8 miles a day on 2 country roads and I rarely ever hit 50mph anyway as I'm usually busy looking at the fields and local wildlife. Left a message to pick them up. Thanks guys.

[Rocco83]

***** him down to $175. The spare ended up being a 31, but the tires still had knobs on them and were practically new. Should've able to resell the rims and have myself a super set of cheap tires.

[Rocco83]

Guy just called me and let me know he has an actual matching spare and another rim to throw in for free and that he would drop it off to me tomorrow. Can't beat that deal. 6 new tires for $175. Sometimes Craigslist brings you Christmas throughout the entire year.

Should fit fine unless you suspension is really sagging. I run 30s on my xj.

[Rocco83]

We'll see cause the shocks on this bad boy are see through.

[rabies]

seen 31"s on a stock xj. very little space in fender well. had some rub at full lock.

instead of a new thread: plz forgive my thread jacking. its relavent.

not sure how to formulate the question
how do you measure tire size? once it passes 225/(75)/16 tall

i have 235/75/16. iv never seen "80" once you get past 75 does it get measured differently.

like..whats the next size up from 75/16"rim?

so you look for 31/32/33 tall tires for your size rim?

[4.3LXJ]

There is such a thing as an 80 series. Kind of rare though. I remember some Q 80s in Buckshots. But a little beyond your size they start reverting to the traditional method of measuring.

[rabies]

^which is? like overall heigth from ground to the top of tire?

[4.3LXJ]

No the number is the height of the bead to tread surface expressed as a percentage of the width. So you take the 225mm X .75 and add to the radius, 8" and multiply by 2 for diameter, or as we would say height

[abebehrmann]

Just so it's clear (it took me a while to fully understand). The metric tire sizes that look like this: 235/75r16, give first the tread width in mm (235mm) followed by the sidewall height as a percentage of the tread width (75% of 235=176.25mm) then followed by the rim size in inches (15 inches). To calculate how tall they are, you need to convert the sidewall height to inches (25.4mm/inch so 176.25mm=6.94inches) then multiply this by two and add in the height of the rim to get the total tire size (6.94inches x 2)+16inches =29.88'' tall. So a 235/75r16 tire would be roughly equivalent to a tire that is 29.9 inches tall with a tread width of 9.25 inches.

[rabies]

uhhhm i think i understand.

I love Craigslist when the person isn't a complete weirdo or not flaky. Those tires should fit pretty well. I've done it before, but my suspension was pretty much new. I got zero flex out of it. Rubbed a little bit as well. Mine were the BFG MT's. Loved em though.

[Rocco83]

Not looking for any flex at all. Right now just looking for tires that will get me to work and home on a flat road so I can earn the money to really work on it.

[HeartTheft]

Is this an XJ we're talking about? If it's a stock JK then 30s fit quite well with no rubbing, I know because my JK uses 30s on stock.

You can pick up really decent TJs for under 5k if you're patient.

[HeartTheft]

Yeah, that's the plan. :) I need an offroader, the JK is nice, but still new enough that I don't like scratches.

[Rocco83]

Just think though. If you find a way to total it out you can get a TJ as a daily, AND a YJ for a trail rig. Best of both worlds. You also will no longer drive the cross eyed brother of the 14 Cherokee.

[HeartTheft]

Awh, harsh, man! Good idea, but harsh! XD
