how to determine scale size tire

[RootBreaker]

ok so i have googled this and also searched here.. maybe i overlooked it..

but my axial is a 1/10th scale truck...
with 5.5" tires..
does that mean in real life it is like 55" tires?

if so then easy peasy...

if not im really confused.. hah..

so my real truck has 40" ground hawgs which on the overly wider than supposed to have rims it is 38.8"

so in 1/10th scale terms... I need a 3.88" or 3.9" tall tire to go scale right?

1.9 ripsaws are 4.3" tall.. so getting closer.. like a 44"?
so would i be a 1.5 tire???

appreciate it...

Your trucks a 1/10th scale you take the tire size of say the 2.2 RipSaw at 5.5"s and multiply it by 10 so it would be 55" tall tire like you said.

so what size or who makes a vood 3.8 zize?

check rc4wd for their tires, i think the mud thrashers are 3.8, might be smaller actually.

edit: dirt grabbers are 3.8, dick cepek mud county are 3.9

The thing is that many boddies are listed at 1:10 size but are not. Some may be 1:12 or even 1:8. The best way is to take the wheelbase of the body you have. Find the actual wheelbase of the full size version and divide it by the rc's wheelbase. That will give you the ratio. For instance look at a 4door Jeep Cherokee. It is listed for the full size to have a 101.4 inch wheelbase. The rc version is listed as a 1/10 scale. But when you divide the wheelbase of the the rc version which is 11.8 inches you actually get it to scale to a 8.6 scale (101.4/11.8=8.5932203). So take a particular tire say a 4.5 inch tall Pitbull RB. (4.5 x 8.6=38.7) so the PitBull actually in scale terms to the Cherokee body comes to what would be about a 39 inch tire.

Very few 1:10 scale boddies are actually 1:10 size. By using that basic math, you can get a much better scale idea of what things will look like.

Want to fin what would scale to a certain size? say you know you have your scale body size figured out. Lets say it is actually (1:9.5). You want your rig to look like it is on a 42 inch tire. Divide the 42 by the 9.5 (your scale size) and you get what size tire to look for (4.42 inch tall rc tire ).

wow, so basically what you are saying is that RC crawlers have insanely large tires--based on scale. I was trying to figure out how to make it look like 33" or 35" tires on my Gen8 but I dont think that is happening...

I think you missed the point of the previous post.

Most rc crawlers are not actual 1/10 scale.

Most crawlers are in the 1/8-1/9 th scale relm based on body size and wheelbase. The new Scx10III JLU is a perfect example. It runs 4.7" tall tires which look to be a roughly 40" tire irl on a Jlu.

I use the system of TLR when determining tire size, but I also have quite a collection.

It also doesn't account for the fact most bodies are designed for 4.75" tires and have wheel wells way larger than the 1:1 versions. A 35" is a perfectly reasonable tire size on a full size Scout but a scale 35" is going to look like a donut in comparison to the cavernous fender openings on the Gen 8 body.
