Lowering vs. sidewall upgrade... ding ding!

Alright so Ive got the new wheels and tires (255/35/20 F, 275/30/20 R)... but after I put them on, I noticed that it definitely needs to be adjusted so the gap is filled in under the wheel wells. Naturally, I've been speculating at lowering it to give it that more aggressive stance and solve the gap issue, but I found that with lowering it, comes certain disadvantages such as scraping issues and having to purchase camber kits and what not. Additionally, I'm also putting on a Kuruma front and greddy sides soon, which i hear are extremely already extremely low as it is.

Anyways.... heres my question:

Has anyone ever heard of just upgrading to a tire with a larger sidewall (like maybe 275/40+/20) to fill in the gap? I already happen to think that our cars are quite low to the ground as it is and it just seems like this would not only resolve the gap issue but also avoid the scraping and extra parts required issue.

I'm not sure what the perks/cons would be to this, which is I guess what I am ultimately asking for. Anyone have any advice? thanks guys!

Wanna Raise your whole car?

Hey i just read your question....If you get a higher profile tire you are going to be raising your whole car. WHen people get high profile tires on trucks what happens?

You are just going to be raising the car and you are till going to be coming into the rubbing problem, especially in the front.

larger sidewalls obviously increase diameter. you want to stay close to the oem diameter or your speedo is going to be off.

it will throw off your speedometer/odometer, potentially mess with your VDC/TCS, and make your acceleration slower overall due to the increase weight and effective gearing. This is a horrible idea.

Your front tires are a bit too big. They should be around 26" in diameter, but those 255's are 27", which is about 3.7% larger. 3% is really about as far as you should go.

And these are far too large. Stock rears should be around 27" in diameter, but this set is almost 29". You'll most certainly have problems with the VDC kicking on more often (like on every turn you make), and your speedo/odo will be way off (almost 15% larger circumference). So if your guages say you're going 65, you'll actually be going closer to 74.
