tyre heights (inflated diameter)

[skid]

Will update once at home instead on phone but heres some pics of our measurements at work of tyre heights.

All measurements were done on a 15x8" rim with the tyre inflated to 30 psi.

Very interesting results.......


Bugger it. Failing to load pics from fone . Watch this space

[skid]

finally managed to get the pics up

as you can see there is some varied heights here and some of them surprised me a a bit.............

theres a couple of 33" heights but the rest are 35" tyres except for a 37" creepy..................

as we get more tyres coming in we will be measuring each one, so I will add to this thread as I go on

37/14.5-15 Maxxis Creepy Crawler 908mm

35/12.5-15 Simex Extreme Triple Block 906mm
35/11.5-15 Silverstone Extreme MT 905mm
35/11.5-15 Simex Extreme Twin Block 895mm
35/14.5-15 Pitbull Growler 886mm
35/13.5-15 Maxxs Mudzilla 875mm
35/12.5R16 GT Radial Komodo MT 875mm
35/12.5R15 Maxxis Bighorn MT 762 873mm

33/12.5R15 Federal Couragia MT 825mm

Hummmm i wonder if the 37 creepy crawler side walls are being pulled in to much if they are fitted to a 8" rim.
Would if hoped it to be at least 25/30 mm taller than the other 35's

37" Creepy should be on an 11 or 12 inch rim.

Are you sure the Silverstone and Simex 35/11.5-15 measurements are around the right way?

Nice one Skid. Interesting stuff and interested to see more. Treps would be nice to see.

Agreed. Had a mates (very near) new 35x11.5 Silverstones and my new 35x11.5 Simex both mounted on my 8.5 rims sitting side by side and the Simex was noticeably larger.

but what pressures were your simexes and your mates silverstones sitting at?

[derk]

These measurements are all good and well, but at what pressures were these measured at?

The rim and pressure need to be identical each time to ensure the only variable being measured is the tyre diameter.

Food for thought.

didn't you read the first post

Yea, I was referring to what shortylux was saying.

Yep, good point.
I can't 100% guarantee they were exactly the same. We had just pumped them both up for tarmac travel and cant imagine we had much variation in pressure.

Last time I was down south I got show a couple of brand new sets of silverstones and on the same rim at the same pressure there was a good half inch difference in height, we also had a older silverstone that was about a inch shorter again, which is about right for the older tyres. I was also told that they had seen silverstones even bigger turn up as well. Strange thing was that the tyres could have the same batch lot and mould number on the side wall. Took sum pics of the different ones inflated on rims, which ill post up when I get back
