Should I be concerned ?

elfasa - 14-9-2012 at 12:32 PM

When looking on my buggy tyres, looking for the pressure range I noticed it said "max speed 20kph"

I've probably been over that already in my first couple of hours riding. Should I be particularly worried about this?

you've been over 40 mph? already? I wanna see the GPS Screenshot of that one. Mine are low speed tires,and they have been up to about 50 MPH. No probs yet.:ninja:

elfasa - 14-9-2012 at 01:06 PM

20kph is around 12-14 mph ! (ish)

I've had mine up to about 40.0 mph and no problems yet. I just hope if one decides to go its with a wimper and not a bang. I think that you can get better tires with more plys but don't think you need to yet.

ignore speed recomendation but not pressure recommendation

At the speeds will go you... I don't see how anything will happen to the rubber. It's just rubber.

The warning may be a general warning concerning a blowout and what can happen if/when a body is thrown from an unknown vehicle(unknow type/stability/weight) using this makers tire BEYOND a certain speed. It's not like the tire will explode, disintegrate or melt at speed......not speeds buggiers go.



....so go fast..!:wee::roll::wee::roll:

I have not yet heard of a buggy tyre blowing out because of speed....

Are you saying Don't fill the tire past the rated pressure ? Or that you should fill them to max. pressure ?

I like my tires a bit on the soft side. With them soft I can ride slightly softer sand.

Don't exceed the max pressure of either the tire or wheel. Otherwise set for comfort/performance.

I have done 66 klicks on grass with do dramas on barrows

Guess I went the wrong way on that conversion LOL

soft in soft sand is good...

Better roll at higher pressure on hard surface.

Lower pressure will allow more contact of tire surface to riding surface. In regards to soft sand..this will mean less 'digging in' better roll and float over surface-especially in turns- and is appropriate.

Fill it close to Max on hardest surfaces-but never more. Less on irregular, bumpy or softer surfaces. Also, you need a minimum of air- whatever that may be(don't want to bottom out and ride/bang rims!).


NOTE: Did you ever ride down the highway and see a car in next lane with a nearly-flat tire and think you should honk and warn them? (they think you're a kook and don't know what you're pointing to and saying) They don't get the warning, continue driving and further down the road you actually see their tire disintigrate to shreds(smoking even!) or you see artermath and them in breakdown lane with shredded tire ?

Seen it a few times. THAT is when speed IS a factor when it combines with super under-inflated tire. If they rolled over tire at 5 mph it wouldn't disintegrate for a longg time- if at all....but at 60+ mph on a super-underinflated tire..it's coming quickly.... with friction and heat doing it's destruction.:shocked2:

Honestly...I really don't know why it says Max Speed 20 kph on tire...?

NEVER EXCEED THE MAXIMUM SPEED RATING ON THE TIRE.



























Mwahahahahaha, now the way is clear for me to climb to the top of popeye's speed leauge table.

Booby he's asking about speed not pressure!! I have gone 40mph on 12mph tires. There aren't many wheel barrow racers going that fast but mine held up.

elfasa - 16-9-2012 at 08:09 AM

Thanks for your help guys !
i am sure to keep them within their pressure limits, i have them at between 13-15psi, as i use them on both hard / soft sand.

As for the speed, I guess its not a problem.

Personally I don't like to buy anything that doesn't come with one of those litlle "Warning! Using this product may cause serious injury or death." cards attached to it somewhere....

Manufacturers need to protect themselves or insurance companies would charge them so much we wouldn't be able to afford the toys :)

Update! better info..?

skimtwashington - 17-9-2012 at 05:26 PM

Ater speaking w/ the venerable buggydanny...a better explanation and logical supposition for the low speed rating is it is rated for a maximum weight load(I don't know if that limit is listed on tire-but likely not)...and so they are considering there may be a load of say 800, 1000 lbs...etc..(but it's unsaid in warning)

My tire just says 'load range 'B'..??

It's an incomplete warning...but if you don't go more than the 20 kph warning, they're covered.

So... to be more clear..... it's a factor of weight bearing and speed... with level of inflation being an important factor also.

Oh..and you'll have to consider road surface...(also gravity of planet you're riding on, what gas you filled tires with..;-))

Your rubber tire was almost certainly not made specifically for buggying.
They are considering a single tire load... you're on THREE tires to divide load weight.

Just don't go faster than this smiley to be safe::roll:

Thanks skimtwashington, that's interesting :)
