you know that the lego tires are often too wide for their diameter or the pattern is only street legal and nothing for real offroad driving.
now i have found some RC crawler tires which fits nearly perfect to the 8110 unimog rims.
the tires came from the german manufacturer ansmann and have the number 211000224
the diameter is 108mm and the width is 40mm
or 4,25"x1,45"- 1,9"
they are ballon tires with a very soft rubber compound and with a foam inside
here some pics




if you know some other compatible third part tires, please tell it us.

Very good. How can i know the price for that set of tires?

You can move your topic here. It would be better to collect all info in one place:)

How do they perform?  Do they slip?

currently i have only two tires so i couldnt test it on a vehicle, but tested with my hands the grip is much higher than the 94.8 tires from lego.

[VFracingteam]

Wow, i think it,s look great at any offroader

[DLuders]

Think of how much better those German tires would look on the 44772 wheels which were used in 8110 Unimog U400, the 8297 Offroader, and to be supplied with the upcoming 9398 4x4 Crawler set:

iam not sure whats your intention with this post, because these are exactly the same rims which i have used

Yes, I know -- those BIG TIRES would look better on the upcoming 9398 4x4 Crawler set than the undersized ones that will be supplied by The Lego Group.  Your big German 3rd-party tires are more suitable for Rock Crawlers than the ones used for the 8297 Off Roader set:

Do you know the weight for one of these tires or if they are heavier than the ones on the Unimog?

[jadedomg]

Thanks for the information, I will have to see if I can find these tires over here as the ones on the upcoming crawler look a little too small.

unimog 66 grams with rim, the crawler tire has 97 grams with unimog rim

Ouch! Those are going to be much harder to drive!! I guess its okay though since we've been blessed with the gray after-steering gear reduction portal piece thingy from the Unimog

do you think that they performing well?

[allanp]

Those tyres are waaaaaaaaaay better!

[efferman]

today arrived my other tire sets. one set i have choosed with steel rims, because they are cheaper. but unfortunately the tires are glued to the rims, so you should look for beadlocks.

[Sheepo]

That tires are fantastic!!!     

I have one question... Can slide the tire over the rim?? as the 94.8x44 tires...

I have the 8297 Off Roader in my hands, and am measuring the 44772 Wheel + 54120 94.8 x 44 Balloon Tire.  The Lego tire's inside diameter is ~54mm (2-1/8").  The 3rd-party tire that Efferman found has 108mm outer diameter x 37mm width x 48mm inner diameter, or 4.25"x1.45" - 1.9" .  The width of Lego 44772 Wheel = 34mm.  

There is a useful RC "Scale Truck and Crawler Tires Comparison Chart" on MyRCBox.com .  The next size larger than 48mm (1.9") inside diameter is 56mm (2.2") -- too large for the 44772 to use without slipping.

no, the tire fits very tight to the rim.

Do the tires slip in the rims when driving?

Tim

[efferman]

i think not, but i will be sure when i have built my modified willys chassis

[tibivi]

Hey,

I have an RC jeep and I tryed it on my trail truck.
The tires don't slip in the rims when driving,and they are better for outdoor use than those from the 8297 set

[efferman]

i have made a testchassis to compare the tires. thanks to zblj for the inspiring beast trial truck. and i have made a short video

i think the performance is better than the performance of the lego tires

[Conchas]

Good demonstration!

I guess the larger tire diameter is a decisive factor for the better performance surpassing this obstacle.
