After reading that informative thread I still don"t have an answer.
I know as much as I did when I first read it yesterday, that a 225/45/16 will fit but not if the 225/50/16 will. But thanks anyway for the smart ass answer all the same.
if i'm not mistaken the stock rims are 16" x 6.5" wide. A minimum of a 7" wide wheel is recommended for 225 size tires so the 225 would probably be too wide for the stock rims. You're probably better off going with a 215

Let's start with "why the hell do you want to use such a big tire on such a small rim?"
The fact is, a 205/50/16 (stock size) is the widest tire anyone should ever try to put on a 6.5" wide wheel. It already has 0.8" of overhang on each side of the lip. Increasing that to a 225/50/16 you now have 1.2" of overhang on each side of the lip. Let's also not forget that the 225 is going to be 0.8" bigger in diameter than the 205. This will make your speedometer/odometer off by 3.3%. The 225 width tire is designed for rims 7.5-8.0" wide.

A 225 tire can be used on a 6.5 rim, and even with the change in the aspect ratio I think the wheel well of the Prelude looks anemic with the low profile 205/50/16 tires. Personal preference. I just want to know if it will clear the struts.

My stock wheels with 205's do not hang out .8"
225 wide tires are good on 7-8 inch wide wheels

Do you konw how rediculous 225's will look on a 6.5" wheel? not to mention its unsafe and youll have an unstable side wall.
What do you mean clear the struts? do mean will it hit any suspension parts or fender? that depends on your ride height and wheel specs. My 225/50/16's on 7" wide wheels with a +42 offset do not hit any suspension parts but rubs the fenders on hard turns (fender rolling will solve that issue)
As I said in my first post "stock suspension" and as I have no aversion to changing wheels, my question was just if someone had factual hands on information as to the application.The guys at 'Hot Prelude' and 'Tire Rack' where the ones who thought it would work. And as for side wall flexing and ride quality at speed, this car (my third Prelude)for me is just transportation. As a member and sponsor of HSR, when I want to drive at speed, I do it at the track. I don't mean to hurt anyones feelings but I truly believe that with all the race mods and suspension improvements that so many people make to their street cars, the inevitable fact remains,fast cars don't make fast drivers.
If I've been rude, it's just been a long day. My first choice in tires was the 215/50/16. I was just curious as to the limits available to me.
Happy 4th of July.
Of course they will work on 7" rims, but they aren't intended for it.
Lastly, increasing the overall diameter will decrease your acceleration.
OP, If none of this matters to you, then put the tires on the car. So what if they look like drag radials.

Why do you want to run 225 wide tires then? You are the one saying that the prelude isn't a race car. Why don't you just stick to 205 tires since you are just commutating. 205 tires are dirt cheap and gives you good mileage.
You would only want 225 tires if you want better performance. If so, get some 7.5 width rims to match. 225 tires on 6.5 width rims will probably lower your performance.

intended? you can use 7-8in wheels for 225's. IF you your wheels and tires to match perfectly then you can go with a 7.5 in wheel.
I have 205/50 Rs-2's on my stock wheels and they dont stick out almost an inch, no stock tires do unless they have a rim protector. Your calculation althought correct, dont work.
225/50/16 dont seem to make my car slower and doesnt really throw off my tach enough to notice. A wider tire does hold better around a corner, but its width gives me a lower top speed.
Ok. I guess you're expecting to see the overhang right at the lip of the rim. Section width measures the tread, not where it mounts to the wheel. The tread most definitely overhangs 0.8" beyond each side of the rim, and that's when the wheels aren't even mounted to the car. However, depending on your inflation pressure, your sidewall will most likely stick out even farther than that. This is especially noticable when you look at the lower portion of a mounted tire. The weight of the car will compress the sidewall, making it bulge at the bottom even more than at the top.
Since you know the math is correct, yet claim that it isn't accurate, just grab a caliper (the measuring kind, not the braking kind). You'll find that the sidewall on the bottom side of the tire of a mounted wheel will be about 8.6" wide (for a 205/50/16). I've done it.
Oh, and the larger diameter makes your acceleration slower and should in fact INCREASE your top speed.

I was under the impression from my tire guy at KAL TIRE that unless i was buying a wider rim i would be forced to use the 205/50/r16 as using any other size would decrease how the car rides, feels, and accelerates not to mention there is a saftey factor by switching tires sizes but using the factory rim. I am not a tire expert so i dont know but i am just relaying the information that the tire guy i go to, gave to me. Perhaps he is wrong but i think not.
I have the answer because I already bought the 225's and could not even drive it out of the parking lot they rubbed so bad. I dropped back one size to the 215's and they worked. They rears will rub when you go over medium bumps until the tab on the outer fender wall wears away or you can simply file away the tab. No damage to tires or fenders.
