Hey currently I run front 235/35/19 on a 19x9 rim abd 265/30/19 on a 19x10 rim.

Reasons I would like to change is I often crack rims, mostly the rear and also tire selection for the rear size isn't a whole lot. It seems all the popular tires I can find on here start at the /35/ profile widht. Like the super sports or the Hankook Ventus.

Tire sizes confuse me so just looking for a general idea of size I can look at that would work well? Like what the lowest profile size you would recommend to avoid cracks?

you could go 265/35/19 or 275/35/19 in the rear but ideally, to match the front needs to get taller also with 235/40/19. you might look into the load rating of your current rims also

Yeah, and I assume doing so I'll have to raise my coilovers more right since the overall height is higher? I'm also debating on just staying as is and going with Firestone indy 500, seems to the only affordable summer tire in my size.

Rims are Avant Garde M359, can't see mto find load rating but they are cast wheels so definitely not the strongest. I planned to upgrade though to a forged wheel after this year maybe.

I would certainly try a 265/35 on the rear, the extra height would help absorb a pothole hit. Although I'm on stock 189's, I went with 235/40/18 and 265/35/18 and I haven't had any issues.

[335i54n]

you may not have to raise the height but depend on how low you are now (if tucking tire, yeah probably). for the price and quality apex wheel are hard to beat but other big makers have pretty decent and strong wheels also, I am looking at the Konig hexaform myself

[TheMidnightNarwhal]

Okay yeah so, it would give it about an inch higher. The rear I can clear honestly the front I think if my tire is any higher it actually touches my coilover? Unless when the suspension is raised it's naturally closer? But the play there seems tight.

I think I'll try another year with the same size to make sure all fits ok.

switch to a 245/35 & 275/30. It's a much beefier setup and fit your wheel size better. With a 235/265 those tires are stretched a bit. Visually it's a pretty decent change. Not sure what the guy is talking about with a 235/40. Makes no sense. a 235/35/19 & 275/30/19 are the same diameter. Switching to a 245 front will make the front tire slightly taller then the rear but it looks fine.

Here's my car with 19x9 & 19x10 wheels and 245/35/19 & 275/30/19. Rear fenders rolled a bit. Pretty sure I could fit a 285 in the back which would be a perfect match to the 245.

Honestly, also consider the rims if you're getting cracks. I recently came to this realization myself. After replacing 4 bent/cracked ESR rims, I realized I could have just bought a set of decent quality rims to begin with and been happier.

What squirt said. What wheels are you on? Some are more prone to cracking than others.

For clarity, are your current tires run flats? Those also cause wheels to crack more often, because of the stiffer side walls.

I'm on 245/35 and 275/30 PS4S. Wheels are 19x9 +29 and 19x10 +40.

[TheMidnightNarwhal]

My wheels are Avant Garde M359s. No runflats!

But guys, I don't understand going for 245/35 and 275/30, when I look at tire comparison websites that setup's sidewall is still as much as I have now no? Meaning my wheel are probably going to crack as much?

And yeah this year was probably the last one with the rims, didn't really plan to budget for a new forged set already so that's why I'm kinda using them again.

[Emilime75]

The point I was trying to make is that many run similar, if not the same, sidewall heights and we don't have wheel cracking issues.

When I was shopping wheels, any time I came across a style I liked, I googled it followed by keywords like "crack" and "bent". It was then that I decided AGs weren't for me as I came across a lot of posts on them bending and cracking.

My search led me to my current wheels, the 437Ms. I love the style, the size/specs and they are forged. I would've actually went with the 18" 513Ms if I found some at a price that didn't rape my wallet, but they're much rarer than the 437Ms and usually quite a bit more expensive. I scored a deal on my mint 437Ms at $1200 for the set.

What I'm getting at is that taller sidewall tires may help, but you're still left with wheels that are prone to cracking and no tire will fully remedy that. If your tires still have some life left in them, I'd start looking for replacement wheels, first.

Definitely not buying wheels this year or even the next if they are still in good condition. Starting this year I'll get a second car to so this one will be reserved to weekends so less risk of cracking.

But for now then I might as well just keep my current sizing if other size don't offer more crack protection. I like the stretched look.

But they keep cracking. Not understanding how that can be considered "good condition". Maybe cosmetically, but a wheel's functional importance is much greater than what it looks like on the surface. Cracks can cause air leaks, sometimes sudden ones when you're flying down the highway, not too mention complete failure where you end up in a wall or another car.

[tcphoto]

Emillime75, I am thinking abut the same setup and would like to see a picture of your car. Does the 437's poke up front?

[Emilime75]

tcphoto, I'd call it perfectly flush in the front. I don't like the poke fitment and I wouldn't be happy with them if I thought they poked out. I have some photos, I'll try and upload them here, always struggle with that.

Yeah I meant cosmetically mb.

So by cracks I mean hairline cracks that develop at the edge of the rim which causes slow leaking. IIRC I think I had 3 total split between my rears and repaired. As I was re-finishsing my wheels over winter I noticed also even my front wheel one has one crack like that but doesn't leak. So I can't say how long that crack has been there.

Since they're hairline cracks I've never really thought it was that dangerous? Definitely don't think the rim is going to crack to the point of if I had a sudden flat.

245/275 definitely have a taller sidewall than the 235/265. On top of that with 9 & 10" wheels those sizes are stretched making the side wall even smaller.

Without a doubt moving from 235/265 on 9/10" wheels has a much different look. I had to raise my car to get the same fender clearance I had before.

[Yotaismygame]

My personal opinion if you want a hassle free setup 8.5/9.5 are ideal on a 3-series when sticking with 235/265 which look right at home on those wheels. If you want a slight stretched looked move up to 9/10" wheels. If you want a setup that will require minor mods move up both tire sizes with the 9/10" wheels.

Ok see now I had a suspicion going stretched also reduces the side wall a bit right? I see alot of post people run 245/275 on those wheels so I think I'll give it a go!

Only worries is added rubbing, I run Bilstein b14 pss coilovers and run 12mm spacers in the rear might have to change spacers or roll fenders another round. The wheels are 19x9 and 19x10. I don't mind losing the stretch look, as long as it's a sporty look and looking at your pic it looks like so!

I'd bet runflats would help, at least a bit.

What offsets are you running now? I'm at 36 & 38. Pretty certain with my rolled fenders I could fit a 285. I've ran a 5mm spacer in the rear with no issues. I really like the 245/275 look. But the 235/265 looked good too. Just different styles.

I thought people avoided run flats and that was one of the reasons. So it's the opposite?
