They ridea hard as expected. Probably zero forgiveness for potholes. No rubbing at all.

DAYYYYUM 25 series... be careful!

They look awesome congrats!

Sprayed01

Ya I do feel a little scared with the profile but they look so good. We shall see.

My exact thoughts.

Nothing new about 25-series. Plenty of guys running them around here. They have the same sidewall height as that 30-series 245.

On the plus side it looks like you gained 50hp just sitting there!! Looks fantastic!

Exactly, HeissRod. "X" Series Tires do not apply to modern tire measurements. They were used for old bias ply tire sizing, though.

In the tire measurement of 245/30/20, the 30 is the aspect ratio of the width. The width is 24.5 CM wide. The sidewall height is 30% of the width or 30% of 24.5 CM. That's 7.3 CM. Using the same formula for 285/25/20 the sidewall height is 25% of 28.5 CM or 7.13 CM tall. Difference in sidewall height between the two is .17 CM.

Now take this information and have fun sizing tires to your heart's content.

Thanks for the info Widelowandfast.

Now this makes me wonder if swapping out the 245/30 in the front for a 255/30 is going to make any visual difference. Im running a 9 inch front wheel and I dont like the look. The wheel sticks out past the tire a lot. The tire shop agree to install a 255/30 tomorrow to hopefully correct this.

What do you think, worth it?

Gunmetal looks great on a black E. May have to have mine sprayed

It'll get you the width you're looking for, for sure. The 255/30 will also give you mathematically a 5.2 mm (10 MM per 1 CM) difference from front to your current rear tire. Now, here's the grey area. The sizes on the side of the tire aren't the exact tire measurements. It's best to get the tire mounted and compare it to the rear tire visually. I'm sure there's a threshold where the tire speed due to different tire diameters will cause issues with ESP/ABS etc. You can also pull the tire specs up on Tire Rack and compare the specs there. 255/30 and 285/25 shouldn't be an issue, IMO.

Oh, and the wheels look great, by the way. I have the 19" Niche Targas on my E63.

Sprayed01

Thanks. Im starting to think 19s would have been a better choice. The wife is scared to drive the car. But man do these things look perfect on the car.

Sprayed01

What size do you have on the 19 inch targas? Btw I love that wheel too. What color did you go with?

Sprayed01

Just followed you on insta. Looks amazing!!

Im on there too @legitstreetcars

Same for YouTube

Sprayed01

Thats me but I did not buy that car.

Continental Extreme Contact DW @ 245/35/19 & 275/30/19. I'll be swapping to a set of 9.5"x19 & 10.5"x19 HRE P43SC's this summer. They'll be 255's and 285's respectively. The Targas I have are Niche's Anthracite finish. Or as I like to call it, Brake Dust Grey.

NW European

Wow, that looks really good. Nice work.

Sprayed01

Put the 255 up front and it looks a million times better. Looks proper now.

HeissRod

Little late to decide that

Sprayed01

Wait till my next thread.....

Redwood415

I am running the exact same aspect tires on my O.Z. rims, Im switching to 35 series on the rears next time around. They look killer but not much there!

Sprayed01

I don't think 35 will fit back there
