beginner information on 1/12 rc12e/i/l tires

[JosephS]

Is there a good thread on here about tires and wheels for the rc12e?

I picked up an rc12e on ebay over the weekend. It seems I have all of the shock rebuild and diff parts I need already

I don't know much about 1/12 tires and wheels and the vintage nature seems to be a bit of an extra challenge.
From what I have caught up the rc12e/i/l/l2 all used the same offset and 2 bolt pattern.

What are the sizes of 1/12 vs 1/10 wheels?

How are foam donuts sized?


Would modern 1/12 front tires work on these older cars?


I just want to put some reasonable traction on it to drive around parking lots and tennis courts.

What are the sizes of 1/12 vs 1/10 wheels?

1/12 rims are ~1.36" tall x 1"(f) or 1.5"(r) wide
1/10 rims are 1.8" to 2.0" tall x 1"(f) or 1.5" to 2"(r) wide

How are foam donuts sized?

Foam OD are trued to the roll out you want.

I think so.

Are all of the inner diameters the same on the foam?

I see this as an option

Are you asking if the ID between 12th and 10th scale foam donuts are the same? If so than no.

Sorry for not being clear. For all of the different OD on 1/12 foam is the inner diameter the same. As well do modern foams have the same inner diameter? Looking a the pictures it's hard to tell if the inner diameters is the same across the foams.

[Frankentruck]

The front inner diameter is the same as the rear inner diameter on a chassis, but not the same between the 10L and 12L cars.

Sorry...I know TM Racing has been producing pan car wheels since the mid 90s, but I don't know if they've changed their wheel sizes over the years.

With 1/10 drag cars you'll sometimes see them use 1/12 scale wheels with taller foams that have been trued to a 1/10 scale OD. That's what those TM foams look like to me. If the ID is the same then they'd just need to be trued down a bunch. The 1/12 wheels themselves might actually work on the left side of an RC12e/i/l, but I don't think they'd work on the diff side of anything earlier than an RC12LC.
