All,

I have 2006 EX-V6 Accord with 17" rims.

I'm planning to change tires and I was suggested to move from 215/50/R17 to 225/45/17. I was told that those tires have better handling and they are more quieter.

Does anybody know if I should decrease the middle number?

What kind of Ultra/High Performance tires you would recommend, because Michelin a way to expensive and not trusted. I have 3 tires changed already for 1.5 year period.

Your speedo will be a little off. Use this link http://www.miata.net/garage/tirecalc.html

Thanks for the link.

But in general: would you recommend to change tire sizes?

There won't be any problem going from 215/50/R17 to 225/45/17. But your speedometer and odometer will be off a bit.

As for an ultra or high performance tire, there's quite a few in that size.

For example, there's:

Kumho Ecsta ASX
Yokohama AVID H4S **
BFGoodrich g-Force Sport
Yokohama AVS ES100
Bridgestone Potenza RE-01R
Pirelli PZero Nero M&S **
BFGoodrich g-Force T/A KDW 2 **
Bridgestone Potenza RE960AS Pole Position **
Dunlop SP Sport Maxx
Bridgestone Potenza G 009

...... lots to choose from.


** My personal favorites

If you don't know what to do, you can't go wrong with the tire size that belongs on the rim, and then work from there. Instead of going the "bigger is automatically better" route, maybe you could check out a given tire the correct size that performs better.

I went through this recently and here is the thread about it.

By no means am I saying what I decided to do is better than what someone else suggests. Things at my end made this the best choice with all things considered.

When I was picking out a tire, my approach was wet performance first, then dry. I wanted to avoid the nightmare of buying tires that feel great on a dry road, but feel like they were greased when it was wet weather.

I bought Continental Extreme Contact because of it's high rating in wet conditions.

I would go with a 225/50/17. With the firm ride that these cars have with the 50 series stock tires, the 45 series will make the ride quality worse. Less rubber to absorb road imperfections. IMO> :paranoid:

..pretty fair statement (above) IMHO..........seems like the 45 series (at least with my stock factory suspension) would ride like a buckboard............

All,

Thanks a lot for your help.

I chose Bridgestone Potenza RE960AS Pole Position and decided not to go too crazy and stick with original tire configuration.

Not to jack a thread, but I didn't think creating another was necessary.

My OEM tire size (what I'm running now) is 185/65/15. I want to change it to 205/60/15 OR 205/55/15

Is 205 too big for a 5.5inch wide Alloy Rim? Should I just stick with 195 like the EX models have?

Great choice!

They are good tires

Just stick with 185 or 195. Shoe horning a 205 on a 5.5" wide wheel is pushing it. You'll need a wheel that's 6" or 6.5" wide for a 205 I believe.

When the tire is wide and the rim is narrow, the tread will tend to not sit "squarely" on the road and the sidewalls won't be sitting properly either.

It's discussed by Dunlop here

Sounds like you made a good choice for tires and size. I wouldn't put 225/45/17's on the stock rims. As Foreign-Wide noted, a wide tire on a narrow rim isn't a good idea. The stock 17" rims are only 6.5" wide on the 06+ Accords. Too narrow for 225/45/17 according to the specs for the tire. Bridgestone recommends a rim of at least 7" wide. I'm sure it can be done anyways, but just doesn't seem to be a good idea to ignore the manufacturers rim size recommendation. The stock 6.5" rims were one of the reasons I got some TL rims so I could put some larger and better tires (Bridgestone Potenza RE050A Pole Position 235/45/17) on my car. I didn't find that my ride quality decreased significantly. Maybe a little firmer, but not harsh.

Question, I have an 07 LX and the stock setup is 205/.../... (cant remember) with 15 or 16 inch steelies.

I wanna upgrade to TL 17" rims and 235 or 245 tires.

I dont know too much about this, but from what I am reading it seems this can throw off the speedomoter and odometer? Is there a way to do it properly so that this effect does not happen? Also, will the TL Type S rims (they are a bit wider I think) fit on my car?

And in general, are there wide tires that work fine in the snow? I go to school in Maryland and live in Boston and don't want to compromise safety, but I definitely like the look of nicer rims and wider tires as well as the performance.

Another question... when I go on tirerack.com and input my car specifications, it says that 215 is the max rec tire size for all the rims they give me. Does that mean something bigger is not supposed to fit on a 4 cyl Accord?

tirerack say this is the recommended tire size. you can, however, pick any size you want.

some 225 tires will sit fine on a 6.5" rim. the goodyears I have can be mounted with no problems on rims 6" - 8" wide.

besides, the 225-45 will make MORE NOISE (depending on the type). but assuming the same type it will have more contact with the road surface so it will make more noise. and the ride will not be as good.

I have a 2007 Accord VP 4 cyl originally equipped with 15" rims.

I now have 2005 Acura TL 17" rims on my car, with the tire size as recommended for that Acura TL as per Tire Rack.

The diameter of the tire/rim combo of the OEM for my car, versus the tire/rim combo for the Acura TL are less that 3/4 of an inch difference which has a negligible efect on the speedometer

My ride is fine and the handling is great!

I chose Continental Extreme Contact tires which are highly rated for wet and light snow.
