If you’re looking to upgrade your ride to the best tires you can get, you’ll want to know the difference between 275/55R20 and 275/60R20 tires, which both fall under the size of 275/60r20 tires but have different dimensions. Are they made differently? How are they different? Which one is right for your car? We answer all those questions and more in this article on 275 55R20 Vs. 275 60R20 tires.
The main difference between 275 60R20 and 275 55R20 is that tires with smaller sidewalls tend to perform better at high speeds.
Will A 27555 R20 Fit 27560r20?
After a quick look, one might think that a 27555-20 would fit on a car with a 27560-20. But in reality, if you looked at both of those numbers separately (27555 and 27560), then you’d find that they don’t quite match up.
So it is important to realize that there’s more to these numbers than just first glance. There are 4 different number formats. These are 255255, 255250, 262625, and 255250.
The format used is based on whether it is for a front or rear wheel. For example, if you have 255255, then it means that you’re looking at a size for your front wheel (the 255).
The reverse would be true for a 255250 where that number represents your rear wheel (250) and 255 is your front wheel.
What is the difference between 275 60R20 and 275 55R20?
There are a few differences between these tires, although they do have many similarities. Both offer exceptional performance and stability in all conditions, and both look great on most trucks.
If you’re looking for a tire that can conquer any terrain in nearly every condition, we’d recommend either of these options.
The main difference is that 275 60R20s will be slightly wider than their 55R20 counterparts, which may not make much of a difference if your truck already has big tires or if you plan to upgrade other parts like suspension or wheels.
You should also consider how much weight your truck is carrying before deciding which size to go with; if it’s heavily loaded with people or cargo, you might want to go with 60-series tires so they can better handle additional strain from heavy loads.
As we mentioned, these tires are virtually identical in terms of performance. Both have excellent grip and stability, good traction on all terrains (especially during inclement weather), and long tread life.
However, as you can see from our graph above, 275 60R20s will be slightly wider than their 55R20 counterparts.
This won’t make much of a difference if your truck already has big tires or if you plan to upgrade other parts like suspension or wheels.

What size rims do I need for 275 60R20?
To start, you’ll need an axle that can support 60 tires. This will be close to 7 inches in diameter and typically associated with a 1-ton or greater truck. What size rims do I need for 275 60R20?: To start, you’ll need an axle that can support 60 tires.
This will be close to 6 inches in diameter and typically associated with a 3⁄4 ton or greater truck.
You will need a rim size of 20” x 7.5-9.5” for 275 60 R20 tires.
Many people often confuse wheel size and rim size. So, let’s clear that up first. The wheel refers to how big it is physically, while rims refer to its width.
Both can be measured in inches or millimeters and referred to as diameter in inches for easier reading.

What does 275 60R20 mean on a tire?
The 275 60R20 means they have a section width of 10.8” and will fit a wheel with 20 diameters. It has a circumference of 103.6” and are 33.0” tall. Meaning they can be mounted on wheels with 20” x 7.5-9.5” rim width.
The R stands for radial and indicates that it is a radial tire. A radial tire is lighter than its counterpart, yet performs much better under higher speeds.
The number following R represents the size of the tire in inches. In our case, 60 means 60 inches across a very large tire.
Will 275 60 R20 fit the Stock tundra?
Just to be clear, if you’re asking will a set of 285 60R20 fits your stock height truck, then unfortunately it won’t.
The clearance with a 20-inch tire mounted on your stock rims is roughly 4 inches o which doesn’t leave much room for any additional width or tire sidewall when compared to 275 or 285.
What I would recommend is either staying with your 265 70R17s or switching to 285/70R17s. Your stock rim will fit those tires as they’re close to identical in width to what you have on now but you’ll gain some additional sidewall for slightly better ride quality.
If you go with the 285s, I would also recommend switching from a 17-inch tire to a 16-inch tire as those are going to be your only options for that size.
What is the largest tire for a stock Tundra?
The largest tire that you can fit on a Tundra without any modifications is an extra-load (XL) 255/70R17. Since almost all of these tires are 6-ply, they won’t fit without doing a little bit of trimming and modification to your stock fender flares.
If you’re not a fan of 6-ply tires, your next best option is a 255/65R18. This will give you more sidewall, making them safer in any off-road situations that might arise.
Can you fit 33-inch tires on a stock Tundra?
Many Tundra owners are interested in the fitment of 33-inch tires with a stock suspension.
Unfortunately, it’s not possible to fit 33-inch tires on a stock Tundra without significant modification and cutting of frame sections.
Getting your truck closer to an 8 lift will make 33s much easier to install. Also, aftermarket lift kits are being made by several companies such as AllPro, B&W and Spacer Lift all designed for easy installation of up to 35-inch tires.
A major reason for not being able to fit 33-inch tires on a stock Tundra is due to its short wheelbase.
At 121 inches, it’s almost 3 feet shorter than a Silverado. It’s only 6 inches longer than a Tacoma.
For example, you’ll be hard-pressed to find 33-inch tires that will fit on a stock F150 due to its extended wheelbase of 137 inches.
