Are you planning to upgrade the set of generic wheels in an ambulance? That’s too easier said than done.
Although you’ve got a few choices like sticking with the steel rims to going for cast alloy ones, the choice has more complications to it.
Before you go for a lightweight set or heavy duty wheels to bear the workload, it’s always wise to know your needs first.
Here’s everything you need to consider before you’re down for the game.
Knowing the right size
Size does matter when ambulance wheels are concerned. Make no mistake; bigger doesn’t promise better. Larger sizes looks great but is that all you want.
As you climb the size chart, you spend more, and even your ride quality comes down. For extreme terrains and off-roading wider tires ensure more traction. You can sure go for the largest tires possible for your vehicle but reducing just an inch in diameter doubles your options. Use a tire size calculator to decide your perfect size.
Understanding the Bolt Pattern
This is simple. You just have to consider a couple of things. You need to know the ‘a x b’ pattern of your wheels. Here ‘a’ is the number of bolt holes in your wheels, and ‘b’ is the distance between the bolts measured center to center. This would be true for 6-lug patterns. For 5-lug pattern, measure from the back of a hole at an end to the center of the hole at other.
Hub-Centric vs. Lug-Centric
Now, another crucial thing is to know whether your wheels are lug-centric or hub-centric. Measuring the size of your center bore is important. Gauge up the diameter of the central hole over the mounting hub. If the center bore equals the mounting hub, the wheels are hub-centric, else they are lug-centric.
Backspacing and maximum load Wheels with wrong backspacing will never fit your truck. So measuring the backspacing is highly relevant. You measure the backspacing of your wheels from the middle mounting surface to the back end of the wheel. It’s measured in inches and varies as per your offset. The hub mounting surface falls even with center line for zero offsets. For a positive offset, the mounting surface is more towards the front side, and vice versa for the negative offset.
Knowing Your maximum load is the next milestone. Never confuse this with the maximum weight load that the wheels claim. For accurate maximum load, multiply that load with four. This would be your maximum load.
So here’s all you needed to know to get the right wheels for your ambulance. Still confused? You can contact the manufacturer, and he would suggest the best. If you have a lift kit, there’s not much to know then. Reading a lot of reviews helps as well. Choose wisely.
