I'm down 50mm with 235/45/18 and no snags so far. Going to stick 245/45/18s on rear soon, there's a few on here who have already with no probs.

 

235/50r18 is probably a tad too big (T5 Sportline OE size)

Better size would be 225/45r18 or 245/40r18 (245/45r18 at a push, but i think it will depend on the ET of your wheels)

 

Hey peeps. Glad I found a thread on this. I need to knwo the exact info. The van I have just bought is lowered 50mm and is on rs6 18's. I think the tyres are 225/40. But I want bigger profile. So these recommendations are handy.....BUT what is the wheel ET I keep reading and how do I find this out with my wheels? :*

T: in advance

 

et is how far the wheels sticks out...the higher the number the further the wheel sits in...most audi rs6 etc are around the et35 mark..sitting nice on the arch..

the lower the et the further the wheels sticks out..tyre size is harder when the wheels have lower et's

your et will be on the wheel somewhere,either on rear or in the middle on some wheels with centre caps..

they were from cmc

 

hi all , ive just fitted 235/50/18 s on mine with a 50mm drop very slightly bigger running radius than 245/45/18 i think. what speedo readings are peeps getting ? ive got 80 mph which is bang on according to sat nav at 3000 rpm ( 2.5 102 )

 

With 235/50/18 tyres when your speedo reads 60mph you will be traveling at 63.5mph

Also do u have any pics many thanks again del

 

Del, unfortunatly it is with cmc springs not had the van fully loaded , 2 rear passengers and the interior caravelle bench is as heavy as it been so far . from what ive read on here peeps not had great success with the cmc s an the eibachs are way , could do with some advise on suspension set up with the 235/50/18 myself ,anybody? . the speedo readings were done with the sat nav giving the real speed , the thinking behind the 235/50 was - ride comfort, price with 101 weight loading, making the van as "long legged" as pos for motorway cruising . suspension advise please before camping gear an tow bar get added ,gary

 

Ressurecting an Old Thread I need to know if 235 50 18 will fit ive got RS8 Reps ET35 lowered fitting the t4srus 50mmHD with full camping interior

 

Bump... me too. I have the exact same wheels and want to know if this profile will work! I have some serious tread issues (MOT) so need some replacements asap and would love to know if this is going to work.

I have 225/40x18 right now and would like a slightly more comfortable profile. Someone must know... come on folks

 

Hi guys. Bit of a newbie on here. I have 235/50/18s on Ronals at 45et and about 50 mm drop on front 40 on rear to allow for loading. Problems start at a little speed maybe 50 60 mph and any uneven road causes rubbing on front. Also the tyres look just too big for width of arch. Will be fitting 235/45/18 personally I think these are the best option by far.

 

Thanks for the response! I will get the van back today so will look for ET rating on the wheels. I'll enquire about 235/45/18 too and report back when I've made my decision! Cheers!

 

I am running 235/45/18 accelera tyres for the last 9 months with audi rs6 reps - good even wear, not much road noise and decent ride to boot. I have 60mm drop springs. once rock and roll bed is fitted should sit perfectly. ET is sensible so just about the perfect match tyre size wise for a comfortable ride.
