5 Reasons to Convert to a 30" Motorcycle Wheel

SMT is the industry leader in 30-inch motorcycle wheels for Harley, Indian, and Metric. It is a significant upgrade over your stock wheels. The large 30 inch wheel will make your motorcycle look more aggressive, give you better stability, and a one-of-a-kind custom look. Installation should be done by a certified mechanic or motorcycle shop due to the modifications required. 30-inch Harley-Davidson wheels are the perfect size to make a statement on the road — turning heads everywhere you go.


Smooth Ride

One of the most common questions at SMT is whether or not upgrading to a 30-inch motorcycle wheel will sacrifice ride quality. The short answer is no – you can improve your ride quality when pairing high-quality SMT wheels with high-quality American Suspension components. Making your Harley or Metric look great and perform even better than it did with most factory wheels.


Rides Like a Cadillac

There are many benefits to having a larger wheel, but the biggest one is the increased Angular Momentum. The larger diameter 30" wheel will keep your motorcycle more stable at higher speeds. Additionally, the extra weight of the 30 inch wheel will help to keep your motorcycle planted on the road. So if you’re looking for a smoother ride and increased stability, a big wheel will keep you straight as an arrow.



A 30-inch wheel is a popular upgrade from the smaller 16 to 18 inch OEM wheels that come standard on most motorcycles. Not only does it give your Harley a show-stopping look, but it also makes the wheel the center point of your ride.



The devil is in the details. We take great pride in our work, which shows in the detail of our finished wheel package. When you ride with the best of the best, you ride with SMT. Forget cheap mass-produced cast rims, choose military aircraft-grade billet aluminum alloy.


Backed by a Lifetime Guarantee

30 Inch Wheel FAQs


Do I need to rake a 30 inch motorcycle wheel?

All motorcycles will need to change the rake when upgrading to a 30" wheel. Give us a call if you have any questions about your Harley's model requirements.


Do I need a new front fender for my 30 inch motorcycle wheel?

Yes. If going from a stock wheel to 30-inch custom wheel, you will need a new fender for the much larger diameter. A fender spacer won’t do it. A new 30 inch fender tucks your tire away and will complement the new rim.

Our 30-inch Fat Katz fenders come in classic and wrap-around styles. They are made of steel and come unpainted.


Do I need a caliper adapter or caliper kit for 13 inch & 18 inch rotors?

When upgrading to oversized 13 inch rotors, an SMT adapter kit is an essential piece of equipment. These adapter kits have everything you need to install 13 inch rotors on your motorcycle. They move the placement of your stock caliper. For 18 inch rotors, you will need a caliper kit, a completely new caliper, and mounting hardware for the installation.
