hi guy's,

basically, i bought a set of wheels 6 months ago and went for the cheepest budget tyres i could find because i want to get new tyres next month for a road trip im going on.

at the mo i have 225/45/R17 tyres and they are far from low profile lol

my first question is, if i was to stay with the above tyre size but go for something like the continential sport contact 3, will this be smaller that the current tyre in terms of profile?

second question is, are the tyres above goint to be able to take a good bashing around the Nurburgring? or would it be a better option to go for 215/45/R17 ?, in theory i am loosing grip potential but the profile size will become smaller but will sturdiness of this tyre compensate for the loss of 10mm of grip?

Thanks

Andy ;)

A low profile does not guarantee high levels of grip. Look at an F1 car, they have fat tyres dont they?

Lowering the profile will make the response feel sharper, but it will also increse harshness, so make sure your choice is based on getting a good sport tyre to suit your car, finding the compromise in size and profile.

The mechanics of grip in relation to tyre width is a whole other can of worms, a good tyre at a pressure to suit is what you need, you can 'over tyre' the car with too wide a tread. Bear in mind that the size of the contact patch with road is related to the tyre pressure, not just its width....

To have a go at answering your first question, various brands will have minor differneces in the apparent tyre size when fitted to a given rim, but the appreance will be about the same.

225/45/17 are the correct size for a mk4, budget tyres are always going to be a compromise to be honest, there's a huge difference in quality between a budget tyre and a mid range, probably less so between a mid range and branded, (conti, michelin, bridgestone etc) as with anything you basically get what you pay for. i'm running toyo proxes t1r at the moment and they're great in the dry, and pretty reasonable in the wet and seem to be wearing pretty well so far, they don't cost a fortune and i really can't fault them. yokohama s drive are a good mid range tyre too, apparently they feel a bit more positive in the wet than the t1r's. have a look at buying your tyres online as i
t'll save you a few quid and you'll be able to get a better tyre for your money. black circle or tyreshopper will sell you tyres online and fitting is included in the price. i've been working in the tyre business for 14 years now and buying from a decent online retailer is definitely the cheapest way to go. if you're after a softer tyre for the 'ring, have a look at demon tweeks, they do more of the higher performance ranges, like toyo 888 or r888, yokohama advan neova etc. these are basically a road legal track day tyre, and if you're after massive dry weather grip these are the ones to go for, although they'l be a little sketchy in the wet! ther's little grip to be gained from dropping to a lower profile, as like has already been said, they'll just feel harsher, and there's more chance of damaging a wheel on potholes etc. wheel alignment and correct tyre pressures will also make a huge difference to how your car feels to drive, a little toe out will give a more positive turn in, a little toe in will add stability but factory settings will give a nice balance between the two. if the car's been lowered, it's worth getting a full alignment set up including camber / caster as this will have been affected by lowering the car, and once your alignment has been set up, don't be tempted to adjust your ride height, as this will throw out all the hard work setting the car up. so..... sort your bushes first, then get your ride height where you want it, then get the alignment done. and you'll have a great handling golf!  :wink:
