Default BBS RS 028/029 Tire Sizes

Howdy,

I just picked up a set of Ferrari 308 BBS RS' for my Volvo 242. Currently looking for tires for them while I'm getting the centers bored out to match Volvo's, and was wondering what a good size would be to pick? Anybody have these wheels and run the stock 205/55/16 (Front) - 225/50/16 (Rear) tires with no spacers or adapters? (Fenders are rolled on my hooptie)

I've searched everywhere and can't find specific details here on TB, or on the internet really.

They're 5x108, ET11 Front, and -2 Rear, 16x7 and 16x8 respectively.

I'll be getting conical acorn to ball seat adapter washers for the lugs, and that's pretty much it for add-ons otherwise.

Thanks for your help!

Without doing maths it sure sounds like that rear might rub the fender. Here's 225-50-16, et20 wheel on a 245

Great pic and a very solid point about not going for that specific tire size. I've only seen a couple examples of these wheels being run on 240s. It's hard to tell what size tires they're running as well.

Thanks!

I ran the exact same wheels on a lowered 240 with 205/50/16.





I also ran them with 205/55 and 225/50/16 on my wagon and they looked too tall IMO, but they did fit and rode great.





I think 205/50 and 225/45 would be great combo but not a common size, would have to run different type tires I'm pretty sure.

Those look awesome! I think for the 242's sake, I should probably stick with a 205/55 16 square set. Personally I love the meaty look of the staggered tireset though. Might take some finagling to make them work.

205/50 - 225/45 would be impossible to have match (unless i go track only with the car )

Thanks. I sold that gold set many years ago but actually have another set now. This set was also gold, but had them disassembled and lips polished and faces powdercoated in silver and waiting to go on my 90 780 Bertone. I spent a bunch of time trying to decide what tire to run on that and still didn't order them yet. 780 does have a slightly wider rear track so probably going square tire setup.

I will say the 225/50/16 I had were very beefy, I think they were potenza tires I ran on the 760. There is some variance obviously between brands.

I did have to roll the rear fenders a decent bit to fit them with a 205/50 on the picture black 244

I do have the rear fenders rolled enough to have a 0 offset 17x9 on 235/45/17 tires fit. I wonder if a 215/55 on the rear RS's would be a good compromise between a thicker tire, and a tire that actually fits...

gotcha. I have used this to get an idea between tire sizes- 215/50 is a size I was considering for my 780

It does seem like the 225's would fit fine on the rears when comparing them to the monster truck 235/45R17's I have on there now

Thanks a ton for your help! Wheel and tire fitment are definitely tough for me to picture for some reason.

Your 242 wants 205/55s up front and 225/50s in the back. Get to it.

I really like the Dunlops I think it's amongst the best in the competitive 200tw class. imo they are a much nicer tire on the road than the r888 (which I find really noisy). Did very well for autocross, lot of grip especially when they warm up. Under 45*F they are pretty hard though.

205/55/16 is what I run for snow tires on the truck, not really the look or feel I want on the 242.

not really...a 205/55-16 is a stock 7/9 size and is a bit too chunky and large diameter for a 240.

The new RT660 and the Yoko A052 are really the new "cheater tires" for the 200tw class from what I have been hearing.

R888Rs sound like you're driving a truck with mud tires on it and they get greasy fairly easily. Had them on my Elise and even in that they were a bit noisy.

Mike’s running 205/50R16 and 225/45R16. Bit shorter. Hence why I mentioned them being 17” sizes, Asher

The smaller option makes it look like the car is on skateboard wheels.

No offense, Mike.

I just wanted to know based on my current offset and tire size, if the stock ferrari tire size would work with the new offset and wheel sizes.

glad you mentioned it, looks like the A052 are available in skateboard sizes and I'm buying tires in the Spring so will do some reading up. I do feel like I'll end up with a set of 17's someday just to open up my tire options, but any of the wheels I want are a ton of money so it's easy to put off for now.

Okay chief, you recommended 205/55-16s in a previous post which is why I mentioned it. The only reason to run taller tires like you are saying is because nothing else is available…245/40-17, 255/40-17, 255/265/275/30-18, etc. A 205/50-16 maintains factory size rolling diameter for a 240. You want skateboard wheel sizes? That’d be a 205/45-16 like I ran on the old ****ter 75. Running a taller tire than necessary (especially if you are doing it for a good reason like it being ton wider than stock), just means more headache and the tire running into the body more.

For a 240, I feel that 17s are the sweet spot for normal sized performance tiresÂ…but even then, they are starting to become somewhat limited in sizes these days.
