Agreed. Can't see any reason why you'd want to go wider.

[Mazzy]

Ok, 8 at rear and 7.5 for front. Is that what TD's are? What about offset? Want them to fill the arches nicely.

[thejoaoserra]

Team dynamics are 6,5 or 7 at the front and 7,5 or 8 at the rear.

More people might join the GB if they did them 16/17"

Or if they were 7 at the front and 8 at the rear...

[Mazzy]

We haven't even agreed on sizes. This is not set in stone... Think 7.5 front and 8 or 8.5 rear is good.

Tds/Oz Fronts: 7 x 16 ET26 Rear 8 x 17 ET35 Bore:65.1 PCD: 110x5 The ats dtc (which rub front and back) are Fronts: 7.5 x 17 ET20 (rub on full lock) Rear 9 x 17 ET30 (rub on arches and chassis depending upon geometry). Really, the oz/td size which is also the lotus size is very good. But you could try something of a half way point between the two to allow a 17in front (keeping it at 7in wide) and an 8/8.5 rear for a slightly wider than 225 tyre.

[Krusty]

Are we saying rear 8 x 17 ET 35 and 7 x 17 ET26 front would be a good options with no rubbing with the fronts?

[ChrisS1]

Titans look good, but need to be much narrower at the rear.

 

I will raise the question with Rota.

 

What widths would be more desirable? 7 front, 8 rear? The offsets would change to be the same as TDs then I presume?

[tibby]

Hello FYI I've got RH rims with these offsets front 17 7j et20 takes a 205 45 tyre (No semi, because there mostly wider) rear 17 8.5j et30 takes a 245 40 tyre (..................................) They also do not rub on oem heigth. Also they've got German TUV on them. (Not that it matters) Regards

[tibby]

No problem! Must say with the 17/17 combo i did have these tyres on a (eibach) lowered speedster: front 205 40 17 rear 235 40 17 This set also did not rub BUT i think when putting a 205 45 17 on a 7.5j front rim it WILL rub on full turn when lowerded (NOT sure of this) If possible to get a 7j front i would go for that. (if you want to go to the 205 route) Best combo would be a 7front and 8rear if you want to play safe. Also depends which kind of tyres you want offcourse... grtz

[ChrisS1]

Narrowest wheel Rota can do is a 17 x 7.5

The depth/dish of the spoke is not as deep on the narrower wheels, so here are photos of each



Here's a picture of the Grids:



17x7.5:





17x8:





17x9:





This is the Titans - 17x7.5 and 17x8 are the same:



17x7.5/8





17x9





I hope that helps, but any questions please fire them on over!

Maybe safer to go with the TD ofsett route? So perfect possible with those rims

[Mazzy]

Chris, pics not working??

 

So how do we get the 7.5 not to rub on a 205 tyre? Change the offset?

 

I got rear tubby wheels on the front of mine currently, they are 7.5 i believe and have a 195 tyre stretched on. Car is not lowered yet, they dont rub but the stretched tyre does not look good at all. Makes the wheel arch look a bit empty!
