275/35/18 Tires: Ford Mustang New Edge Fitment Guide

Modified Ford Mustang Cobra Terminator with a turbo kit

Installing 275/35/18 tires on a Ford Mustang New Edge (1999-2004) is a popular modification that can provide improved handling and performance. In this article, we will discuss the benefits of installing this size tire, as well as outline the steps necessary to complete the installation.

Installing a 275/35/18 tire on the Ford Mustang New Edge will increase the car’s cornering ability and provide better grip. This size tire is also wider than what is typically found on factory New Edges (245/40/18), which means you’ll have more contact patch with the ground for improved braking performance. Additionally, the larger contact patch will provide traction, as well as optimize your acceleration.

It is an optimal tire choice if you want to widen the track or run fender flares, but be aware that it may give your Mustang slightly different handling characteristics than you’re used to due to the larger contact patch. Therefore, take the time to get familiar with how your car handles before heading out for a spirited drive. They improve the stability while cornering, by reducing the body roll, but the turn radius will be affected.

Will they rub up front?

In some cases they tend to rub upfront (fender or sway bar to be specific) as it depends on the rim width and offset. Chance are high they would rub on 18×10 rims, but they look very nice in combination with the ender flares.
