Right now we have 275-50-15's on 8" welds and we had to put a stop on the rear axle so if the car sunk real low in the rear the buldge of the tire wouldn't get into the fender lip. We were looking at 275-60-15's which are 3/4" narrower but 2" taller and wondered if they would get into the fender lip. Are any of you using 275-60-15's and could tell me how your clearance is.Thanks

A 275 is a 275, the 275/60 is the same width as a 275/50. The difference between the two is the height, if the 275/50 rubbed the 275/60 will rub even worse.

the 50s will be a little wider, they have a bigger contact patch from what i've seen, i have 275/60 mt's and ive also had nittos. the mickey's are wider than the nittos but the didnt rub at all after you bash in the inner fender's and obviously there is no room for quads. I am using a 15x8 draglite with a 5.5 inch backspace, i didnt have to touch the outer lip of the wheelwell. it hits ocasionally on big bumps but if you careful its not a problem.

A 275 is NOT a 275, the chart in that link shows Differences in width on a 275/60 and a 275/50

Your wrong the 50 series has about 1/2" more width than a 60 series depending on the brand tire some may be more some less but the 50 series is wider . Know what your say before you speak .

better read up:
Section Width
Following the letter(s) that identify the type of vehicle and/or type of service for which the tire was designed, the three-digit numeric portion identifies the tire's "Section Width" (cross section) in millimeters.

P225/50R16 91S

The 225 indicates this tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel. This measurement is also referred to as the tire's section width. Because many people think of measurements in inches, the 225mm can be converted to inches by dividing the section width in millimeters by 25.4 (the number of millimeters per inch).

225mm / 25.4 = 8.86"

Sidewall Aspect Ratio
Typically following the three digits identifying the tire's Section Width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio.

P225/50R16 91S

The 50 indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43". If this tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall.

275/50R15 has a sidewall width of 11.3 inches and a tread width of 10.4 inches.
275/60R15 has a sidewall width of 11.0 inches and a tread width of 9.5 inches.

that is straight off of the Mickey Thompson website which is all REAL WORLD measurements not some calulator.

A 275 IS a 275 look here http://www.procomptires.com/conversionchart.htm

Do you realize 275 is the width of the tire in MM???????????? 275MM is 10.8 inches period!

Those web sites are for a ballpark figure if you want to know the actual width of the tire go to the manufactures web site and look it up I think the know how wide there tire is and will tell you what width wheel it was measured on .

LMAO look at the rim widths! You guys have no clue.
The 275/60 is measured on an 8" rim, the 275/50 is on an 8.5" rim.

FOR THE LAST TIME 275 mm IS 275 MM. end of story!!!!!!


off M/T web 3753R P275/50R15 26 X 11.50R15
3754R P275/60R15 28 X 11.50R15

Same width different height !!

This isnt Rocket Science, just try to use a little common sense. 275 millimeters is 275 millimeters.

I see both of your points, but in real world 275 is not always=275. 275 nittos are way smaller than some other 275s I've seen. It's like shoes. I wear a 10-11 depending on the brand, but they all fit my feet. Also it comes down to how they are measured.

I have seen 275/50 and 295/60 both on 8 inch rims and the /50 was noticably wider.

So if the tire is the same width then why did they use a wider rim think about that . All a narrower wheel will do is pinch in the side wall bead .

Spruce must be another guy that causes trouble with his ignorance and gets kicked off boards and comes back as someone else just to do it again . Sounds like someone that is a scammer and doesn't really know about cars. Couch potato racer are you?
