I have 15x8 with 5.5 bs welds pro stars. I just bought a 275/60/15 from Micky Thomson and they look nice but they look really big does anyone have these rims and tires on there car?

I have a lite pull and roll already done on react with stock suspension on the car but I just need to know if anyone else for these on without a prob... I also have stock breaks and this is going on a 97 240sx s14

Please in trying to mount them tomorrow but once I mount them I own the tires. so I want to know for sure that they will fit under my car before I mount them. I seen other people with my size but there not MT so the MT might run wider Idk please anyone ASAP that can answer this thanks much!!!

Kinda hard to figure it out without an offset. Its its not 0 or less offset, I dont see why you would have an issue. Only thing I can do is compare how much bigger those wheels are over the oem wheels. I dont expect it to rub at stock ride height unless the car is gonna squat like crazy.

205/55-16 4.4in 12.4in 24.9in 78.2in 811 0.0%
275/60-15 6.5in 14.0in 28.0in 87.9in 720 12.5%

The car is set up to track it so yea it's hard squatting and the backspace is 5.5 on a 15x8 I just want to know if it will tuck under or will it stick out? I want it tucked up under the wheel well flush look

Quick math...8j~205mm. Divide by 2=103mm. Backspacing 5.5"=140mm. 103mm - 140mm = -37. So those wheels are 15x8 with roughly -37 offset.

Look up S14s with 10j -12, that should give you an idea where the rims will be sitting. Then you have to factor in the 275s so it'll be poking out alot. My guess is roughly 2" at stock ride height.

What's making it stil out the 275 should I get it lowered to a 255 and can I still keep the 60 or will that be to high? Will I run on the inside?

You got all the space in the world inside. Wheel will stick out no matter what due to the offset. Do you have any other option rim wise? Something with a lower back spacing? I'd shoot for something in the 3.5-4" backspacing if my math is right.

No stuck with 15x8 with 5.5 back space. What if I change them for a 255/60 will that help? I have t mounted yet so I can change them if I mount them that's it I'm stick with them

this is my other set its there xxr531s there 17x9 front and 17x10 rear the offset is 20 in the rear this is how it looks 275/40/17s

I can't see the pix since photobucket and crap is blocked at my work. But the answer is no, not even going down to 265s will save you.

Using your current rims as a reference 10j +20, comparing it to the 8j -37, those will stick OUT another 32mm and worst that what you have now.

Disregard, it should be +37, not -37.

They are sticking out because of the offset. Wheel size wont be able to get you shorter on the rim. Try uploading some pics of the wheels and tires into the thread as an attachment so we can get a better idea

Apart from the offset being positive as you realized, you also didn't factor the fact that rim width is actually larger than 8in, 8in is measured to the inside of the lip, but backspace is measured to the outside.

According to something like this http://www.readylift.com/Images/tech-wheeloffset.gif the offset is around +25

You'll be fine, however you will not be able to have a low ride height with those tires.
