searcher Posted March 4, 2008 Report Posted March 4, 2008 Someones got chance of some cheap tyres then :lol: :D :lol: Quote
mk2vr6 Posted March 4, 2008 Report Posted March 4, 2008 10mm difference! not much but due to the loading of the vehicle I'd say no! the chances of dropping the tyre lip into the rim may be enough for a decent tyre fitter to say no! http://i48.photobucket.com/albums/f245/bashaben/low%20stuff/26coolstuff6.jpg Quote
Rusty Nail Posted March 4, 2008 Report Posted March 4, 2008 Great pic Mk2vr6. In reference to the above pic; The big question is, why would you want to put smaller tyres on your rims? Having to stretch the sidewalls so distorting the tyre, affecting ride, wear and handling, also exposing your expensive precious rims to damage from kerbs, stones etc??? Can't quite see the attraction myself, but each to thier own I guess. PS. Gregers, by reducing the width, you will also be reducing the diameter too (as the sidewall hight is a percentage of the tread width), but not enough to worry about though... :lol: Quote
mk2vr6 Posted March 5, 2008 Report Posted March 5, 2008 from what I can gather it's a drifting thing, allows you to run a cheaper low profile tyre, stretch it and it gives you a stiffer side wall like an expensive tyre, ther are also several flaws in the practise! exerpt from Dunlop Corporations recommendations for rim width: "RIM WIDTH Correct rim width ensures flex at the designed flex point in a tire sidewall for optimum tire performance.If the rim is too wide, the flex point moves towards the rim area, causing heat buildup in the lower sidewall, which reduces tire life and could result in failure. Either too narrow or too wide of a rim can result in uneven tread/pavement contact pressure causing uneven wear and potentially reduced traction, or increased vulnerability to bead dis-lodgement. " Wider rims may offer some performance advantages over narrow rims. A wider rim increases the distance between the beads, which results in a straighter sidewall, which stiffens it. This results in quicker steering response and higher cornering forces.Negatively, the straightened sidewall transmits more road shock to the wheel and suspension, placing greater stress on chassis and suspension parts and delivering a harsher ride. The straighter sidewall exposes the rim, making the wheel more susceptible to damage. Quote
gregers Posted March 5, 2008 Author Report Posted March 5, 2008 adrian :lol: :lol: you were correct, thanx peeps knew i had (heard/read)something about this but as always thought id ask the experts on there opinion,think i will stick to whats allready on,many thanx. regards gregers Quote
snapper Posted March 5, 2008 Report Posted March 5, 2008 Gregers, i ran 205's for 6 moths as i got them for nowt, yes you have to be aware that you have 10mm less and they should still be reinforced and have the correct load rating but if you are aware then you take the risk.I have now replace them with the correct 215's this time part worn, but in reality they are as new with pressing marks and proper yellow test stamp on, again at 35 per tyre as opposed to over the 100 new, i will take my chance but be aware.
