Advice on tire size

I have ordered a set of 20x9 25offset 20x10.5 38 offset wheels

I would like to run a 285 in the rear or if possible a 295.

what are the pros cons of running the wider 295 vs the 285 and what would be the recommended front tire size?

Thank you in advance

I run 20x9 ET25 and 20x10.5 ET35 with 245/35/20 and 265/30/20 because I am lowered. You could easily run 295 or maybe 305 on the rears if you are not lowered.

I am lowered on HR Springs..

I would at minimum like to run 285 if possible but 295 would be ideal..

Your Car looks great! Well done

295's would look better than 275's the car comes with. I put 10mm in front and 12mm spacers on rear and I'm still looking for wheel well to be filled a little more in rear

No, stock 275's with 12mm spacers. I want to go to 295's since it's a minor increase in width but will still have a visual difference

Also still would like some advice on the tire size, would a 295 rear and 255 front be okay on a lowered M550? HR springs

Yes, it would be okay. Just make sure your overall tire diameter (height of the tire) is consistent in the front and rear.

Yes, those would be good choices. Just make sure your rear wheels will be at least 10" wide (so 20x10 in your case) for the 295 tire. Looks like you ordered 20x10.5 so that will be perfect.

You could technically run a narrower wheel like a 9.5" on that size of tire, but 10" is the minimum recommended wheel width for a 295 tire. Anything less than 10" on that tire will make the tires buldge which isn't ideal.

Put up pictures when you get them mounted!

Thanks for the response. Def will! Their a custom forged version of the OEM wheels with some changes, size offset, elected for a 3 inch concave stance in rear and went slightly darker on the color vs oem...waiting for them to arrive now!

So, did you put 295/30/20 in the rear? Got any pics? My buddy selling a set of used 20x9 wheels and I'm thinking of buying them and fitting some continental tires in 295/30 also.

You can do a 265/35-295/30 with those wheels easily. If it were me, I'd try a 275-305 on those wheels but I'm not sure how stiff your springs are xD

On my M550i I'm running 20×10.5 in the rear and 20×9 In the front with 275/35R20 and 305/30R20's. I had the 285's and 290's, but liked the look and ride with the these the best. No rubbing issues.

Hi all and merry Christmas

I would like to know if someone has tried to put 265 front and 295 on OEM 20 wheels. I am going to buy a G30 540i rear wheel drive and would like to improve traction since I am looking for a stage 3 and hopefully more than 500hp.

Thank you

What are your wheel offsets?

I did go 295 fit no issues.

This is the size to go with IMO

Here are pictures without my floating OEM caps.

Hi, thanks! I'm not sure of the offset, but the wheels are BMW MSport Wheels 86281, 86285, 20×10.5 R 20×9 F. Hope that helps.
