Interesting, i thought having more friction would improve stopping distances.
Perhaps reduce MPG but i didnt imagine it would be less safe. |

It's often overlooked, it's not the friction between the tyre and the road but the effectiveness of the brakes themselves. If you think of the radius of the tyre as a lever pivoting around the centre of the hub, the bigger the radius the longer the lever so the more rotational force exerted at any given speed. So to create the same braking force on a bigger radius tyre at the edge of the tyre takes more effort at the brake rotor which is much nearer the centre of the wheel. Bigger tyres = slower acceleration + reduced brake efficiency + lower engine revs at a given speed |

Ross, If you adjust the steering stops, you can get a better turning circle, regarding mud up the side of the car, we made some small plates that fix to the bottom of the wheel arch and the top of the mudflap, you can see here that they aren't really visible and do actually stop quite a bit of mud!

285's on 16 x 8.5 inch rims
I have them delcared on my insurance as I have a agreed value. They may be (stil can't quite make up my mind) up for sale soon as I am thinking of going onto 255's on the boost. The sale of these should help towards the cost.

High praise indeed thank you. Was thinking of getting rid of it and replacing it with a DCPU but keeping it now. still have soem bits to bolt on yet like the new exhaust
Will let Chris know you said "hi". Boy |

That's a common misconception, but as long as your brakes can generate enough torque to lock the wheels (which is true of most modern vehicles) then that is NOT the case. It may depend how you define efficiency, but the stopping distance would remain the same. Yes you will require more braking force to produce the same retarding torque at the ground, but if you can lock the wheels then force is not the issue - traction is. Therefore larger tyres may actually brake better due to the larger contact patch. However things such as the increased moment of inertia probably cancel this out. Confusion can arise because larger wheels will make your car accelerate slower. This is because, unless you drive a dragster (or you're Killer90), there's not enough engine torque to spin the wheels in every gear. Last edited by twopoint6khz on 5th Apr 2012 12:59pm.

Another potentially limiting factor to bear in mind when fitting wider tyres, is the clearance to any undershield that you may have fitted. While the back edge of the tyre may clear the steering stops (which you can adjust) the front edge may foul a steering guard (which you can't adjust so easily).

Allways thought the white lettering displayed on the outside of the wheels looks a bit camp.

Camp? That's a new one
Lettering inside/outside? You might as well ask "do you like Marmite?". |

as for the white Lettering the tyres are over 5 years old and still going strong
