Genesis 2013 sedan Rear tire size question

[Daveac]

Hi , i am new to this just bought a 2013 genesis sedan 3.8 and i would like to know what you guys suggest me about the rear tire size ,
I would like to go 275 , i know i will need to change wheels because the stock might not take it really well ( not sure) i have the stock 18" wheels would like to stick to 18" because the roads here are so bad ,

Let me know your recommendations about the complete REAR wheel sizes and tires

Thanks alot in advance

There is a whole thread on tire sizes with different wheels but I run 20x10 rears with 275/30 next time I get tires I think I'm gonna move to 305/30 for better stance

Would your tires be flush with a 305 rear? And of not what offset required to be perfectly flush? I'm thinking the same on my 5.0 Rpec

I have 20x9 +25 front 20x10 + 40 lowered on storm springs which are about to be available for sale as I bought brand new customized DS series bc coilovers. About to be like an inch lower in the rear maybe 2 in the front. soorrrry I don't have that many pictures of fitment on this phone..

You may not want to run a 305 on an 18 inch wheel, the only viable sizes which are 305/40 or 305/35 all seem to be R-Comps or drag radials. However if you were to run 275/40 or 285/40 on a 10-10.5 inch wheel with roughly a +35 offset there's a lot more options and I'm 99% sure they'll fit with no issues.

The guy asking about the 305s is not the OP. I'm assuming he knows that I'm talking about running a 305 on a 20in wheel..
and no 265/35 front 305/30 rear is same diameter as OEM and the most optimal size(this is the biggest I would go anything more and you're gonna have a plethora of issues.. now for 305 a 10.5 or 11 is more ideal 20x10 wheel is the absolute bare minimum size you're ever put a tire this size on otherwise performance starts to be sacrificed

Oh my apologies, I was paying attention. You're 100% right, I wouldn't go any smaller than a 10.5 wheel for a 305. To the OP, I would try to lean towards a staggered 255/45 and 285/40 setup as it's just a hair shorter heightwise than factory. 275/40 is 15mm shorter and 275/45 is 12mm taller although you do have more tire options.
