The correct fit for larger custom wheels has been written about in countless articles and on many web sites. Here is just a quick review. One inch larger diameter custom wheels with a lower profile tire are usually safe to use. This method is called Plus One. The Plus Two method consist of a custom wheel 2 inches larger in diameter along with a tire that is two inches lower in sidewall profile. Using the Plus One or Plus Two method will make your upgrade to larger custom correctly and in most cases the new custom wheels and tires will fit in the wheel well with out rubbing.

To stuff a slightly larger custom wheel and tire under your fender is not an impossible undertaking. So, what can be done if a bigger than normal custom wheel and tire rub slightly on the inner fender lip as you are turning a corner or with added weight from one or more passengers? The most popular way to make those cool big rims fit is to roll your inner fender lip either using a baseball bat or a professional fender roller.

The old school method of flatting the inner fender lip is as simple as using a baseball bat. This method has a higher probability of damage than a professional fender roller. However if done slowly and properly a bat will give you equal results. Typically the baseball bat is placed in between the tire and the fender, with the fat part of the bat on the tire. The handle of the bat is at the 6 o'clock position and is tilted to apply pressure to the inner fender lip. By pushing the bat down it act's like a lever to bend the lip up and out of the way. Use a hair dryer to soften up the paint around the inner fender lip so it wont crack.

A more practical way of rolling the inner fender lip up and out of the way of your tire is a professional fender roller tool. The fender roller tool is simply bolted onto the hub of your vehicle and a roller applies firm pressure against the inner lip of your fender. With the use of a hair dryer to soften the paint around the lip and a slight pressure in an arching motion, you can bend the lip up and out of the way slowly and much safer than a baseball bat. For about the cost of one new tire, you can purchase a professional fender roller.
