johnny9999 Posted June 10, 2019 Report Share Posted June 10, 2019 I'm about to change my 18" Cadiz for 19" replica black Pretoria wheels. My tyres need changing, so now seems to be the time to take the plunge. Am planning on Pilot Sport 4S 235/35/R19 tyres. I was just about ready to hit 'buy' and now the question of 8j or 8.5j has come up. They have suggested I buy 8.5j. But other people seem to have bought 8j. In my confusion, I went to a VW brochure to look at the 19" specs and it says 8j. I'm not even sure how much difference it makes? Can someone clear up my confusion? I definitely want to get the same spec wheel front and back, so should I go for 8j...? In terms of tyres, I assume its 235/35/R19 regardless of J...? But wouldn't the tyre be stretched if the wheels were wider, and if they are stretched, then less depth of tyre would be hitting the road and so more uncomfortable (because they'd be stretched/flattened by having a wider rim). Trying to get as many opinions as possible on what people have chosen and why. Thanks Quote Link to comment Share on other sites More sharing options...
johnny9999 Posted June 10, 2019 Author Report Share Posted June 10, 2019 I've also seen mention of "19 inch Pretoria replicas 18x8 ET45". In this context, I have no idea what 18x8 means, nor do I know what ET45 means. Any ideas? Quote Link to comment Share on other sites More sharing options...
BobbyT Posted June 10, 2019 Report Share Posted June 10, 2019 18x8 means 18 inch diameter and 8 wide.... ET is the offset, so 45. OE offset is 52 I think, so these will poke 7mm out into the arch. Quote Link to comment Share on other sites More sharing options...

golf7.5r Posted June 11, 2019 Report Share Posted June 11, 2019 235 on an 8.5 will stretch the tyres. I'd go with an 8" width - the offset is already enough to fit the arches better than oem prets. Quote Link to comment Share on other sites More sharing options...

FamousAfroJay Posted June 11, 2019 Report Share Posted June 11, 2019 I run 8.5 wide with 235 tyres and ET40 offset. It sits almost perfectly flush with no need for spacers. R-Estate 1 Quote Link to comment Share on other sites More sharing options...

Still not decided if it's the right decision, but at least I've made a decision! Quote Link to comment Share on other sites More sharing options...

Many thanks, Darren Quote Link to comment Share on other sites More sharing options...

This means I don't have to worry about getting spacers now I believe? Also, could you put a picture up showing the tire to arch gap now you have the racing line springs fitted please?

Hi Darren, what style did you go for? I have this full side on picture from a rare occasion that the car was clean. BobbyT 1 Quote Link to comment Share on other sites More sharing options...
