225/40 R17

[Guest]

hey team..

iv got 215/40 17 in the RS at this stage. wheels are 17x7. Just wondering if i will be okay to fit 225/40 17's.

Two reasons,

1. i want to get rid of the chinese brand kingstar on at the moment

2. to lessen the gap between wheel and guards. i had put in dobisport low's but the car never really went that low.

Thanks is advance.

Have you actually found some tyres in 225/40/17??? Cos that is a strange size and usually not available (in NZ anyway). Very few companies actually make that size. You sure you're not meaning 225/45/17???

[Scoobydoo]

I thought I had that size but then I remembered they were 18".. not 17". I checked Toyo's site and they don't list one in that size, but do have listings for Proxes4 and T1R in 225/45/17.

With changing to a 225/40 you are only going to lessen the gap by 4mm (tyre is 8mm taller overall).

Plus a 225 would perform better on a 7.5" or 8" than a 7".

I say stick with a 215/40

215/45R17 on my GC8. My speedo is bang on perfectly accurate too ;D Had the 40s on but it looked like poos, too much gap in the everywhere.

Compare this to this.

Running 215/40 R17 on my wagon at the moment. Will probably go back to a 45 profile because i keep thinking these ones are flat.

Considered going to a 225/45 but theyre just harder to find so didnt bother, plus i was told the 7" rim is a bit too small for them

225/40-17 is a real oddball size.

A straight swap for 205/50-16 but almost no one makes tyres in the size.

A search thorugh US tyre retailers show only three hits; two Hoosiers and one Nitto.

Another vote for sticking with 215/40

[Guest boostcut]

are you sure you will have enough room for the tyre to not hit the strut? as my legacy was like 3mm off hitting and they always stung me at wof time.

[Guest]

cheers for the help guys....

.... there seems to be a lot of room between my wheels and even the strut.....

thats the link for firenza tyres.... shows 225/40 17's there.... dont know how good it will be....will give them a call next working day.

just a question...why is 225/45 not good for 17x7 rims ? is it just too large ?

[Guest keltik]

McPhail....inspires confidence LOL

Ive also wondered why you shouldnt fit 225's onto a 7inch rim. If the tire is too wide for the rim then im assuming you wouldnt get all of the width in contact with the road? Totally guessing

Done a few ads for McPhail...makes me lul every time ;D

Too wide or too narrow - does it make a difference?

Given all the information above, you ought to know one last thing.

A rim that is too narrow in relation to the tyre width will allow the tyre to distort excessively sideways under fast cornering. On the other hand, unduly wide rims on an ordinary car tend to give rather a harsh ride because the sidewalls have not got enough curvature to make them flex over bumps and potholes. That's why there is a range of rim sizes for each tyre size in my Rimwidthulator above. Put a 185/65R14 tyre on a rim narrower than 5inches or wider than 6.5inches and suffer the consequences.

[Guest keltik]

I love that guys site, have spent many happy hours reading through it.

His calculator also shows 215 as the widest you should go on a 7inch rim.

Go 215/45R17 on a 17x7 rim, 40 series is just too low a profile...and there should be plenty to choose from, factory size for thousands of cars...

[Guest]

cheers team...

really need to get rid of the kingstars on them now and fix the misfire.

I misread as that ;D And thoroughly agree.

Even a Toyo T1-R would be an excellent upgrade, and nice and cheap at that

Depends on the car, driver and road.

45-series is more comfortable.

40-series more responsive but harsher.

lol @ SET THEM ON FIRE

[Joker]

they aint that bad....

[Guest]

they are okay when road is dry,

i little bit of rain and the drivability goes down the drain... imo.
