Maybe this question has been made over and over but will these tires fit?

front 245-30-20 on 9x20
rear 285-25-20 on 10.5x20
what offset should I take?

I have a C63 PP, nothing changed on the suspension.

And what about tire choice, I'm thinking between Michelin PSS and GY eagle F1A2

thanks in advance!

I can tell u for a fact that GY F1's run wide. I have 275's on 9.5 rears and i have minor inner wheel well rub on the felt. Same can be applied to PSS's. 275's are as wide as you can go for those 2 brands.

CarHopper

^ You can make 285's work... It just depends on the offset you go with.

However, OP, on a 10.5 rear that may be pretty tough. I've use this picture a few times, but here you go. This is mine with a 275 PSS on a 10.5 rear with a +52 offset. I am also lowered. As long as you remain stock height you'll be fine but it might look a little funny having such an aggressive/large wheel while remaining at OEM height. To really get a nice look I recommend lowering it and taking the 285 down to a 275.

What offsets did you have in mind?

Also, 245's will be fine in the front, again, just assuming you're going with a standard known offset and not something ridiculous.

275's look very tight already. I've seen 285's Nittos, but not GY or Michelins. Any rubbing with your setup?

CarHopper

Only in the most extreme circumstances. Again, thats on a 10.5'' with a 52 offset. A 10'' wheel and a 55 offset should fit a 285 without too much headache involved.

I don't know the offset ofthe wheels, I'm going to look tomorrow for a new set.

How about cast wheels? I never visit tracks, only road use.

I've been looking for wheels today.
I liked the BC HB05 very much. Has anybody experience with these wheels?
I think it will be 20x10 in the rear, 10.5 is too much for me
Here some pictures, what do you think?

CarHopper

As far as style, that is up to you and your preference. I wouldn't let someone talk me out of a set of wheels because they didn't like how they looked especially if I liked them.

10'' wide in the rear is probably the most popular setup among c63's with aftermarket wheels. I think most go with 19's but it somewhat depends on the conditions of roads where you are.

Overspooled

Exactly! If you like them go for it! I think the last ones and the first ones looked pretty good, I would also like to know how much offset is flush for a 10" wheel with some 275's!

Roswell

I would stick with 275 on a x10 wheels. 285 is doable, but very high chance of rubbing when lowered.

It must be nice to have the opportunity to try different set of wheels on the car before buying. I like the first one the most.

Mort

I am running 19x10 with an ET +53 and Michelin PSS 275/30/19 and H&R springs and it is pretty flush. You might go as low as +50 but no actual experience with that low an ET.

Roswell

Mort, r u rubbing with 19x10 +53mm & 275/30/19 PSS?

My new wheels are 19x10 +50mm & 275/30/19 PSS.. And I know I will rub occasionally.. So shaving my wheels 3mm is out of question, so maybe 265/30/19 PSS might clear?

I run a 19x10 ET +53 with a 265/30/19 Continental Extreme Contact DWS and have zero rub over everything. I'm running H&R coils about 1 3/4 inch above the lowest setting on the coils.

I previously ran a 19x10 ET +53 with 275/30/19 Falken Azenis 453 and I would spray rubber shards all over the rear panels when hitting so much as a small pothole. Forget about having more than 3 people in the car too. I had to raise the coils up about 3/4 of an inch just to be ok for 2 people in the car.

Roswell

Good infos Jonhy, thx for sharing ur real life experience. I used to be on 19x10 +53 w/275/30/19 & only had a slight rub on the passenger rear. So this will be my first experience with +50mm in x10.. Hope it's not too frequent & annoying or else I will follow ur footsteps & go 265/30.

Rolf de Graaff

This one wasn't in stock so I couldn't try but I really do like this one!
