After running 35s for 4 months, 33s for 12 years, etc. Rocky sections of trail that required me to get out of the Jeep to scope out a route don’t require that anymore. I noticed the difference right away My All-Terrains’ performance for one – better traction (on dirt and in the mud) compared to the same tires in the 33″ size. What I do know is that I haven’t seen 8th gear…ever. I’m doing an oil change at 1500 miles and will know more about the power loss then. As for power loss, I can’t speak to that yet because I’m only at 1200 miles and haven’t really been above 4000 rpm. This translates to a firmer on road ride. They are stiffer and heavier than C rated tires. The tires are closer to 34.5″ in diameter. My Sahara with 35×12.5 KO2s on 18×9 rims with a Mopar 2″ lift. 33” Speedo readingīelow are the physical differences between 33” and 35” tires both on a 16” rim Measurementĭifference between 35-inch and 315 Tires (Metric vs Standard mm) What 35” Tire Owners Have to Say? The below table will give you an indication of how the speedometer reading is affected between a 33” and a 35”. The increase in tire circumference means the actual speed will be higher the faster you travel. This might throw out your speedometers reading slightly. In the case of 33” tires, the diameter will be larger and have an increase in the aspect ratio.

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.

Yes, it gives you the extra 1″ of clearance, however, there are negative aspects to it as well. But a 35″ tire is going to put more strain on the drivetrain to perform and to haul the 4WD over obstacles off-road. This added weight has a direct effect on fuel economy, performance, gearing, and other drivetrain components. Gas Mileage Difference between 33 and 35” Tires – MPG vs SIZE 35” tires and your Drivetrainīecause the weight sits below the sprung suspension it falls part of unsprung weight. We have since established that the 35” tire will offer approximately 1” of clearance on the axle, but let’s look at some other factors you need to consider first. I guess that all depends on what type of wheeling you enjoy doing or if the truck is a dedicated off-road rig. The question then is, how often will this situation arise, and will the added hassle and cost of fitting 35’s justify the number of times you’ll actually NEED it? This will highly depend on what kind of off-roading you are doing. For example, most SFA trucks with 33s will be just as capable 99% of the time compared to those with 35s, however, there will always be a situation when the larger tire will outperform. What you really need to be asking is, what’s more, important to you, and are the added complications that are part and parcel with big tire upgrades worth it. Yes, sure, a larger diameter tire will in many cases be better when off-roading, provided your vehicle has enough torque to move those heavy tires off-road and your drivetrain can accommodate the additional weight. Enough Torque to accommodate the added unsprang weight.Those factors include but are not limited to: Yes, there are other more important factors than squeezing the biggest tire possible on your 4WD.
