Hi all ,I have found a new set of 27'' tyres for the right price.
My question is ... how much if any will they change the performance of my Revolt.
Cheers Dan

Mr. Dan,
You might want to measure the stock set, to see what the difference is in diameter.
A bigger Diameter, will feel like a small gear change, higher.

Bearfoot is right. Measure them both. Sometimes the printed dimensions vary from tire to tire. Not all 27" tires are exactly 27". Also the taller tire will give more top speed but you might lose some accelleration.

If they are at really good price, I would say go with it....
because if you dont get them, and you buy samller ones, then latter on you might be saying... why didnt i get the 27"

give them a try and if you dont like them keep them as spares for the desert, or re-sell them if you can....

I run bighorns 27'' in the rear and I dont think ill ever change to a smaller size... they have worked great for me, and I have even gotten the holeshot at glen helen a couple of times... the problem is my driving... lol

- just my point of view...

by the way, what brand are they?

Thanks for the reply guys they are
AMS Swamp Fox 6 Ply

Sizes

Fronts 27 x 9-12
Rears 27 x 12-12
I can get them for $250 AU so I am gonna get them and give them ago.

I am chasing more top end speed as Mick and i are about to have our first race meeting on the easter long weekend and we will be competing against Hyaboosa and ZX 14 powered buggies.

I am also looking for the 6ply tyre as we have already staked or standard tyres in the bush and limping back 20 miles with a flat doesn't do the rims much good.
Dan

cool,good luck at the races....
keep us posted how they work....

Hey Dan
When you get those mounted and have some time to play, try turning the front tires backwards ( switch left to right) and let me know if you get more traction in a turn. My theory on directional treads are that they work fine when they are being powered, as in the rears, but on the front the tread pattern is working against itself. Turn the wheel to one side or the other and look at the deflection the tread is exposing to the ground. I think it works better going in the wrong direction. I tried it with my Afterburns and I could tell the difference.
I might be stirring something up here but there is a reason tractors don't run directional tread on the front. The same with duners.
Just an idea.

good to know, I also run afterburns in the front...
Im gona give it try one of these days and see how it works....

did you notice the difference on dirt or on the dunes?

I will give it a try and let you know how it goes
Dan
