Who run 20"?

andrey77 · May 28, 2023

Want to buy Ferrada alloys but think the 19" may not make me happy, want to avoid rubbing on front mud covers.

As far as I am concerned that 19" were already impractical and as big as I would go on RC. 18" probably would be best suited for the car in terms of economy/comfort/handling... 19" are sacrifice for the style. The 20" obviously is even further compromise... if you want the looks then sure go for 20"... I reckon the arches on RC can even take 22" if you have right widths and offsets.

I mean it is not exactly complicated, if you put lower profile tyre and keep wheel size the same they will fit - https://www.wheel-size.com/calc/?wheel1=265-35-19X9ET45&wheel2=265-30-20X9ET45&fcl=50mm&wcl=30mm&scl=50mm&sr=0mm you can do same comparison on fronts.

Think Lexus only ever went as big as 19” on the RC and at that size tyres are 35 profile (I think). I run spacers to adjust offset and can get intermittent arch rubbing if I hit a bump a bit hard. With the right ride height 19” looks fine!

I agree that the 19" is ok for RC but I'd like to get nice look with concave alloys and 19" sizes don't have deep enough size. Also rubbing problem stopping me for the bigger size but I read different stories from the American forums and people say some 8.5 width have rubbing, some 9.5 without issue. Thanks

I run original 19" wheels with the spacers all round 15 and 20 mm and have no rubbing issue at all but the ET of my alloys just not make me happy for 100% but in the same time not really make me sad )))

That will all depend on offset and tyres - again you can use the tool I have shared to calculate different offsets and tyre widths. Ideally you should go and measure how much space you have now as a starting point and it will tell you if your wheels will rub (at least in theory, works fine for the rear, but not so much for front).

8.5 would be very skinny wheels for 20".

15-20mm spacers I would say is pretty usual offset to space wheels more nicely. That is what I would go for myself. I think around 25mm the wheels should be level with arches, but anything more than that and you probably will start rubbing on normal offsets.

There is a red example on autotrader that's on 20". Maybe you can contact the seller for some pointers.

If you ask me... it just looks wrong... but maybe that is just me.

I do believe I got the wheels which came off this car originally!

This car have wrong tire sizes on the rims and the car is not lowered that's why it is looks a bit strange.

More likely... wheels have wrong offsets and are wrong width... so who ever fitted them had to stretch the tires to avoid rubbing... or maybe it was their "stylistic choice"... who knows...

IMHO wheels are just too big and looks like a cart wheels... as always what is too much is always not good.
