Moving from 1.9 to 2.2 on Redcat Gen 7
So, are you wanting to upgrade or fit 2.2 tires to your Redcat designed for 1.9 sizes?
If this is the case, you need to be aware of a few things.
So, exactly what are the difficulties of upgrading to 2.2-inch tires?
One of the main problems that you’d run into while upgrading to a 2.2-inch tire size is the outside diameter of the 1.9 tires. But you can overcome that problem. You just need to perform some major trimming to make it work.
Or else they might rub a bit worse than the stockers. And also it might seem to be slightly wider. Other than that, everything else should be fine.
Also, in the case of running small 2.2 tires like those around 5 inches work quite well.
But not to deny that it kind of plays havoc with the centre of gravity. To compensate for that you may add weight to the axles.
This way you have to give up some durability. But are Redcat gen 7 even Redcat RCs if some customization cannot be done?
At present, regardless, bigger tires are supposed to be the better ones. All the big players in the tire market seem to be preferring the 2.2 sizes. And thus, the smaller models seem to be disappearing.
Because most of the time, the 2.2 size allows the tire to conform and flex. It also delivers incredible traction to the RC cars. At the same time, the inner tire delivers the support for the rig.
This way your tires will not fold over while turning. Or even when they are side-hilling. They will still work perfectly.
The foam inserts that come with them are also reusable. Plus, they will not break down or even get flat spots.
One thing to keep in mind while upgrading to the 2.2-inch tire is that the tires may lose their gripping capacity. If that’s the case, then try soaking it in grease for some time.
However, beware that not all grease can be used to get this task done. Some of the greases that increase the gripping capacity of your tires are given below:
- WD-40 – This is the one you should pick when you try to make your tires more grippy. It’s very well known among the RC community.
- Lucas Oil Red”N” Tacky Grease – This is a great substitute for the WD-40. It gets the job done plus it inhibits rust and oxidation.
Using these will definitely help your tires to be more grippy.
So, to conclude, the 2.2 tires will not be a problem. You just have to make them fit the body.
