LaaLaa's skinny rovers
 
I have strong motorcycle trial background as well as 1:1 offroading. I have noticed during years the fact, that for best traction (in hard terrain) you need large amount of contact pressure under your tires.

IMHO new light weight crawlers are unable to have enough contact pressure with traditional tires. You can get more pressure with hard foams or cutting thread pattern but both ways have negative side effects.

Soft rubber can also give you more traction like tire softener chemicals or super sticky combound, but it's as good as clean it stays. Or as long the thread is not folding down under traction. Pink rovers are good example of that.

I have had a long time dream of extra narrow "trial bike-like" tire, but any manufacturer hasn't done anything even close to that.
Last year when I decited to build new light weight SuDu Pro-Totype I decited also to fulfil my rubber fatasies:wink:

Here is my answer for many many questions about my tires.
They have already proven to be capable for succes.
2nd place in Europe's biggest comp Supercrawl-13 in Germany and victory in norther Europe's biggest comp Nordics-13 in Sweden !!!

Ladies and gentlemens, let me introduce THE 2.2 Red Dot Rover.

http://forums.offipalsta.com/picture...ctureid=133680

It's made with cut'n shut method from 1½ 1.9 red dot rover threads and 2.2 white dot rover side walls. Here is comparison pic for few 2.2 tires found from my shelf. All tires are empty, no foams inside

http://forums.offipalsta.com/picture...ctureid=133682

And here is one "inner secret" pic. It's very time-consuming process to cut all seams to as round shape as possible and to right dimension and glue everything without distortions. I might be little too perfectionist with all that work but at least I know that thay can't be made better and all seams will hold 100% of any possible forces.

Foam setup is quite difficult in these tires but I ordered some prototypes for testing from Crawler Innovations.

And this is how they look under my SuDu Pro-Totype.

Extremely Cool!! You did a phenomenal job on the cut'n'shut!

I may just have to give this a try!

Nice work, look very clean. I have always been a rover fan. Still on my rig most of the time.

I bet these reds grab.

Nice write up mate. You the new Finnish supplier for foams i guess :lmao:

Very neat job on the cut n shuts. What Tomi and Douwe shared with me dosent do justice to how good a job you did on them.

Is great to see they working well for you on your SuDu Pro. Will be interesting to see if anyone can replicate your sucsess with all the copies being made by others.

Nice clean work on the cut n shuts Laalaa"thumbsup" Thank you for your order of foams. There should be plenty to test with Laalaa. I included some sample pairs of comp cut and I hand shaped one pair of your ultra narrow 5.5"s in the comp cut style for testing as well. I've really been enjoying Narrow and Short tires myself on my pro rig.

I WILL be building a set of these for myself in the near future! Do you have a picture of a 2.2 White Dot Rover mounted on a .8-1.0 inch wheel with foams compared to your Red Dot Rovers mounted on a similar wheel with it's proper foam setup?

Trying to compare height between the two...and tire profile. I might want to go a little shorter on mine. 8)

My current wheels are 20mm wide and I'm going to use about same width plastic wheels with glued tires, after I have found best foam setup.

Sorry, I don't have any white dot rovers mounted to the narrow wheels. I will take a pic if/when I have somethin to compare with wheels and proper foams.

Very cool... I can hardly wait to start testing the set I have :D did you get a set of foams like mine to test?

Yes, one set of foams looks same as yours

That's an old trick I did with my Tamiya TXT that I saw on a TXT in an old Australian comp video from the Mudcow days. As well as a pair of Proline 2K Mashers for my 2.2 comp rig I used for a while. I liked em, but went back to the 'put more rubber on the rocks' train of thought. Holes were a problem as the tire found more holes instead of spreading the gap and not getting sucked in.

Here is next set for one of the best drivers in Europe. I hope to see these on finals at Nationals 8)

Tires are only pre-mounted for different foam set-up's to plastic DE racing and HPI wheels w/o glue

Nice work on the cut-n-shut. How are you looking them?

I tried a narrow set of Sedonas last year and could not get them dialed in. Ultimately gave up on them. :roll:

I thought mine were tall and skinny @ 5 5/8" on 1" VP SLWs with custom foams, but your Rovers are awesome!

I really love these tires. No rubbing even with extreme steering angles, grips better than regular tires, light weight, looks better IMHO etc etc

Sedonas have absolutely too big lugs, they will be bouncy or you need to cut all lugs to many small lugs.
