What Is The Size Of A 35 Inch Tire
When comparison a 35-inch tire to a 315 wide tire, yous are basically comparing two completely dissimilar measurements. The 35" is a metric value and refers to the width of the tire multiplied by the aspect ratio, which is the meridian of the sidewall, x2 because there are 2 sidewalls per tire, divided by the cycle inch, plus the wheel size… Phew!!! That's a mouthful and a lot to digest at once and then allow's break information technology down into a simple formula.
Yep, 315 wide tires are the same equally 35" tires although 315 is the tread width in millimeters and 35″ is the tire diameter. 315/lxx/17 is usually the accepted metric equivalent size for standard/imperial 35-inch tires.
Let'south meet what that looks like in a formula form
Tire Size: 315/70R17 (35")
- 315 = the metric width of the tire measured in mm
- seventy = the meridian per centum (Attribute Ratio) of the sidewall
- (315 width x .70 = 220.5mm)
- Divide mm past 25.four to get inches
- And then….. 220.fifty x 2 sidewalls = 441mm (divided by 25.iv = 17.36″)
- 17.36″ + 17″ wheel = 34.36″ approximate tire bore.
Permit'southward now expect into this in a bit more detail
Are 35-Inch Tires the aforementioned as 315's (Metric Vs Imperial MM)
Metric tire sizes tin be a scrap more complicated when it comes to understanding what size they really are.
Let's meet what that means.
Metric vs Imperial Millimeters
Understanding the divergence between metric and imperial is handy when information technology comes to tire sizes considering you lot tin can get really specific. There are and then many different tire sizes available today so knowing the difference can mean finding that perfect fit for your truck. A elementary way to differentiate is Metric is measured in milliliters and imperial/standard is measured in inches. That'southward it!
So when it comes to tire production there's no official mold that each tire manufacturer uses, however they utilise their own which basically ways there's no set industry blueprint. So the 315/seventy/17 is usually the accepted metric size for 35" tires, even though the physical diameter of the tire tin vary from manufacturer to manufacturer. Two different 35" tire brands can easily vary in true diameter.
This means certain tires are smaller than 35″ like a 34.6" and some will be slightly larger, depending on the make and overall structure. Then, this means a particular 35-inch tire can be somewhat wider in width than another. They are like in metric size simply there are slight differences in construction, weight, pattern, load rating, ply ratings, tread depth, etc.
I way to detect out the exact diameter of a tire is by going to the tire manufacturer's website and checking the manufacturing specs on that specific tire and so comparing "apples with apples".
What Size Lift for 35" Tires – Ford F150
The minimum requirements necessary to fit 35x.5 to a Ford F150 are a 4" lift kit and an aftermarket wheel with a more negative offset for improved UCA (Upper Control Arm) clearance. A more affordable option is a 2.5"-3" leveling kit with wheel spacers on the stock wheels combined with fender, torso, wheel wells, and bumper plastic trimming
Fitting 35" Tires with no lift – Jeep Wrangler
Fitting 35" tires on a Jeep Wrangler JK with a stock suspension requires the following:
- Removal of splash guards
- Fit a Rear Spare Wheel Spacer/Extender
- Fit Wider Aftermarket Wheel Flairs
- Leave the front end sway bar continued
- Plumbing fixtures larger bump-stops
Then basically, yes information technology can exist done just not without some boosted modifications first. If your intention is to go off-road, information technology is highly recommended to fit a minimum of 2-3" elevator to exist able to disconnect the front sway bar to take advantage of the Wrangler's legendary articulation. Don't forget the larger bump stops or you'll be picking upward fenders on the trail. When flexing, the wheels volition scrub heavily against the wheel arches and mayhap rip off some plastic if you don't accept it deadening. It won't be a pleasant experience off-road – believe me!
Fitting 35-inch Tires On Your Truck
Bigger tires are the single most effective method of gaining improved ground clearance. This is especially of import for overcoming obstacles in an off-route situation. There are however a few limitations, especially when information technology comes to IFS (Independent Forepart Suspension) 4WD vehicles.
Let's at present look at a few factors to consider when fitting 33" tires on your truck.
Elevator Kit
Before yous even consider plumbing equipment 35" tires on your IFS truck, y'all'll need to take a minimum 4" elevator kit installed. Depending on your truck, sometimes this isn't enough, since y'all'll nonetheless need to make boosted modifications to prevent scrubbing at full lock. This is peculiarly truthful if yous want to retain full functionality and articulation which is important for off-route. If y'all decide to get 4" or higher, beware there are serious implications to whatever IFS suspension, but more on that later.
Who should fit 35" tires? At that place are mixed opinions when it comes to large tire upgrades, and depending on who you inquire, you'll get differing opinions. I give it a Hell Yep! If you can – why not? In fact, I am currently planning a 35" tire upgrade on my truck! The added clearance, aggressive wait, and improved traction and stability in my stance is well worth it. Information technology comes at a toll of course.

Bicycle Offset
Wheel offset or backspacing is a gene that gets little consideration, and it can create complications if you're not certain exactly how much restriction caliper clearance is required. The trouble here is, y'all don't desire to go too negative offset on the wheels else you risk likewise much bicycle "poke".
What is the difference/meaning of backspacing vs Offset?
Backspacing is the altitude measured from the hub mounting surface to the inside edge of the wheel. When you lot decrease backspacing, yous proceeds more inside bicycle clearance. In that location is a fine line between keeping the tires in the guards and preventing scrub on arches, UCA, Brake calipers, etc.
Beginning is measured in mm and generally refers to how your wheels sit down inside the wheel wells. You get positive and negative offset wheels. When information technology's positive the imaginary line is more towards the forepart and negative means the mounting surface is more towards the rear of the rim creating a deep dish upshot.
Fender & Arch Trimming to fit 35'southward
Usually, there are a few plastic liners on the inner fender guards that need to be massaged since they will scrub at full articulation. And then get comfortable with your Stanley pocketknife and cutter and practice some trimming of those bike arch/guards where they are making contact. You might even have to practice some curvation rolling, depending on which truck you accept and how much space you're working with.
Be mindful of the inner guard pinch weld and the inside of the fender flare. They usually demand some trimming, depending on the tire and vehicle. Fender clearance and backspacing get hand-in-hand with tire width. A wider and taller tire will require more bike arch clearance and room to motion when flexing off-road and when turning at full lock. Don't forget virtually your bump stops. Manufactures seldom mention annihilation about bump stops when selling you intermission components and it'southward vital.
When you clasp oversized tires into a wheel curvation without lifting the truck, yous'll need to trim away a lot of the inside fender and arch plastic to allow the tire to tuck behind the arch when turning and flexing off-route.
Will the 35'southward throw out your speedo?
When you upgrade from a stock tire to one with a taller aspect ratio (Sidewall), increasing the wheel circumference, your speedo can be thrown out. In the example of 35" tires, the diameter will exist larger and have an increase in the aspect ratio. This might throw out your speedometers reading quite a chip. The increment in tire circumference ways the actual speed you are traveling will be higher than your speed reading and get worse the faster you lot travel.
The below tabular array will requite you an indication of how the speedometer reading is affected from a 32" (275/70R17) to a 35" (315/70R17).
Speedo reading | 20mph | 30mph | 40mph | 50mph | 60mph | 70mph | 80mph | 90mph |
Bodily Speed | 21.4 | 32 | 42.7 | 53.4 | 64.one | 74.8 | 85.5 | 96.1 |
Below are the actual differences betwixt the stock 32" tire and the upgraded 35"
Measurement | Stock Tire (275/seventy/17) | Upgrade (315/seventy/17) | Differences |
Diameter | 32.2″ | 34.four″ (874mm) | +vi.eight% |
Width | 10.viii″ | 12.four″ (315mm) | +14.eight% |
Sidewall | 7.6″ | 8.7″ (221mm) | +14.five% |
Circumference | 101″ | 107.ix″ (2741mm) | +6.8% |
Revs/Mile | 627 | 587 (365mm) | -25 |
Conclusion
We have mentioned quite a few variables to consider before dropping a load on expensive oversized tires. Y'all should showtime make up one's mind what the chief application for the upgrade is. Is information technology purely for aesthetics or will you need maximum practicality, off-route ability, while maintaining maximum articulation?
