encee Posted February 5, 2006 Report Share Posted February 5, 2006 Okay, having recently (this week ) had some 18` Monza II`s fitted to my steed, the owner of the tyre place, where I had them balanced and fitted, reckoned it was advisable to put 38 psi in, all round, as it would avoid the alloys being dented if I ran into a pothole, or something similar. My local VW service dept., however, recommended the same pressure as the standard 17`s. Any thoughts on this, anyone ? Link to comment Share on other sites More sharing options...
mikemod Posted February 5, 2006 Report Share Posted February 5, 2006 I have the 18" as standard and the fuel flap says 2.4bar all round (35psi) for half load. I have hit a few potholes, as the roads over here are dire, but thankfully no damage yet. Link to comment Share on other sites More sharing options...
RedRobin Posted February 5, 2006 Report Share Posted February 5, 2006 I would be inclined to take VW's advice on this one and follow the fuel flap. Link to comment Share on other sites More sharing options...
GTiMK5 Posted February 5, 2006 Report Share Posted February 5, 2006 I would go with a couple more PSI than what VW suggest so 37-38 would be fine. You will get longer life from your tyres, just the ride will be slightly harder, this is why manufacturers reccomend lower, to give a better ride.

stevie_d Posted February 5, 2006 Report Share Posted February 5, 2006 I always run my tyres slightly over pressured. If you're at a track day then bump the pressure up to begin with and let them down as the tyres get hotter...but be careful not to burn your fingers Link to comment Share on other sites More sharing options...
encee Posted February 5, 2006 Author Report Share Posted February 5, 2006 Cheers gents. I was initially under the impression that 2.4 bar was 34 psi, so I thought I`d compromise between the tyreman`s advice, and VW`s, and put in 36 psi, which I have at the moment. However, having now checked, I find that 2.4 equates to 35.27, so I`ll probably stick another psi in, and settle at 37. For anyone that was wondering, BTW, I haven`t noticed ANY difference in ride quality, or road noise, going from the 17`s to the 18`s (which I was initially bothered about), but the 18`s, as some have said, really are "a work of art" and complement the GTI perfectly. I`m now soooooo........pleased that I bought the Monza II`s, instead of the BBS`s. Link to comment Share on other sites More sharing options...

Simonl Posted February 6, 2006 Report Share Posted February 6, 2006 Speaking of 18"s, Red your car is crying out for some!!! before... after... all those in favour say aiight! PS: Sorry mate, but it's for your own good! Link to comment Share on other sites More sharing options...
Snoopy Posted February 6, 2006 Report Share Posted February 6, 2006 On the subject of potholes if you want to check for damage always check the INSIDE edge of your alloys not the outside face edges, Its the inside that get damaged as theres no strength in the alloy at this point. Jack the car up and spin the wheel and look at it from under the car, (easier if you have a wheels free ramp of cause ) and see if its still round or take it off and have a good look at it. A mate of mines flattened his 18" alloy on the inside, It happened along one of the roads along from me when i was following him, he hit a pothole i of cause did the same DOH!, luckie for me i have the 17s on mine and mine are fine. He's contacted someone that says they can straighten it so we will see how good it is when fixed. Link to comment Share on other sites More sharing options...
stevie_d Posted February 6, 2006 Report Share Posted February 6, 2006 Take lots of pictures of the pothole and contact the council. Sue them for the cost of a new alloy. I would and I don't agree with the whole sue culture, however we pay enough road tax, vat on new cars and tax on fuel to be able to demand decent road conditions. The council will most likely pay up rather than fight the case as they don't really have a leg to stand on. Link to comment Share on other sites More sharing options...

Simonl Posted February 6, 2006 Report Share Posted February 6, 2006 18"s are harsh on potholes, but then again so can a 16", it just depends on the overall setup. Link to comment Share on other sites More sharing options...

Snoopy Posted February 6, 2006 Report Share Posted February 6, 2006 iirc If they can prove that the road was inspected within a certain time frame iirc 3 months they can get out of it. Link to comment Share on other sites More sharing options...

martininwillerby Posted February 11, 2006 Report Share Posted February 11, 2006 First of all I must say that RED's car does look good with those 18" Monza's on ,just like mine does...... Was this picture taken after the suzzie mods.... And those quods make it even better.... On the subject of PSI,I'd been to fill mine up and had checked the tyers PSI 29/30 all round...Now reading 36 PSI all round and the ride is much bettter 'on rails like'.... I will be checking mine a bit more often from now on... Link to comment Share on other sites More sharing options...
RedRobin Posted February 11, 2006 Report Share Posted February 11, 2006 Pic was taken after sus mod but only lowers the car 5mm. I'd rather spend the money on AP Racing brakes (which fit both 17s & 18s) than just on 18" alloys for prettiness reasons. Link to comment Share on other sites More sharing options...
JonoNZ Posted February 11, 2006 Report Share Posted February 11, 2006 But the 18's look sooooo good. Theres no comparison, especially when seen side by side (17 vs 18). Link to comment Share on other sites More sharing options...

[/ QUOTE ] Jono,... looks apart you may have a different view if you kerb them. I suspect they may be dearer to refurbish because of the finish.
