40's or 45's
I just bought Racing Hart S7 17" x 7" rims. I was just woundering what size tires to go with 40 or 45 series, would prefer 45's. THinking of probably Kumho 711 Ecsta's. I also have the Eibach Sportline lowering spring kit.
Thanks.

I have 205/40/17 Ecsta 711's on Sportlines springs also. I really like the tires compared to my previous Z rated that were the same size. These are much softer and quieter. I considered 205/45/17's but couldnt justify the cost difference for 5mm more of tire.
^^^ yeah, what he said!!

Rep Power: 417 if you want 45s.. go with 205-45s... 215-45s are a little too thick... put it in the tire calc and you'll see the 205-45 is a better fit...
if not 215-40-17 is a good one too...
stay away from 205-40 and 215-45

Rep Power: 0 215/45/17 is the widest you can go without rubbing and to maintain the same oem ovreall wheel diameter (keeps speedo accurate).
For example: I have 214/45/17 on SSR Competition wheels (17" x 7.5"). I have less than 5mm of clearance on the inside sidewall before rubbing. On certain situations, usually when my tire pressure is down by 2 or 3 psi and while turning, I will get very minor rubbing. There is no sign of damage or anything. Just a bit of minor rubbing noise. In my situation, I have to be diligent with my tire pressure.
If you have 17" x 7 wheels, you may be able to go 225/40/17. But you are really on edge of rubbing. Depending on the make of tire, it could definitely rub.

Rep Power: 417 The reason why I dont like 215-45 is cause its too thick.. you cant slam the car... Its similar to my 215-40-18s... I'm down to like a 2.5" drop but it still looks high cause the tires so big... You would have a similar problem with 215-45 which is why I recommend 215-40s or atleast 205-45s.
