Changing alloy size

[wifiwupding]

My Ignis sport is running on 185/55/15 their only 5" wide and badly corroded so ill be buying new fatter ones after crimbo so would there be any disadvantages if a went to 205/45/16 7" the radious will be very similar to stock or should i stick with 15s and go 195/55/15 6.5", i know changing to 16s will make a firmer ride but how will it affect the handling i dont want to mess it up

check the manual and also see what options are available from the factory. You need to tell the insurance co. if going outside of OEM wheels....

You need to be careful if you're changing to wider rims, that you don't end up rubbing on the wheel arch or suspension assembly on full lock.

Suzuki probably built it with 5" wide wheels for a reason

Have you checked the difference in the price of the tyres?

Volvo tyres do that as a factory fit.

There is only 1.1% difference in circumference in your new tyres so the speedo shouldn't be affected much

If you fitted 195's instead it would be -0.44% difference, but you'll need to fit skinnier rims (6.5j ish)

You're talking about fitting wheels that are near enough 40mm wider, and putting tyres that are 10mm wider on them.

Maybe you need to re-think this.

No, the original was a very narrow rim for the tyre.

You do need to consider this though:

You need to understand that there are limits on what tyre widths and aspect ratios will fit on what wheel widths, and that there are also combinations that are considered optimal. Unfortunately this information is hard to find; I recently saw a large pdf full of tables for different tyre sizes showing the range of wheel widths and the optimum wheel widths, possibly from Continental, but I haven't been able to find it quickly, sorry.

I'm sure it will look nicer but part of the trade-off is that you'll be increasing unsprung weight which will make the handling worse and the slow down the acceleration.

Not exactly, having to change the tyres to a lower profile will.

Rule of thumb for sporty applications is tyre width dim = rim width dim + 1" eg:

you used to be able to buy the ignis with optional 16" alloys which were fatter than 5" but not exactly shure how wide, i thaught lower profile tyres = better handling because theres less movement in the tyre wall

[Gizmo!]

I wouldn't want to mess up the handling on a Suzuki Ignis.

It might suck.

[wifiwupding]

I think i will just stick to 15 then but just get wider ones, probably 6.5", im looking at Speedline Turinis and Oz Ultraleggeras

[davepoth]

You need to be careful with the offset of wider wheels, to make sure they don't foul on the suspension, body or brakes, or overload the wheel bearing.

[Jayho]

Except for the fact that the Standard Enkei's sometimes look a bit lost in the arches of Ignis Sports, there is absolutely nothing I can fault with them...

Before I managed to get my hands back on a full set of enkei's the last owner had put on a set of alloys (not sure of the make) which were lower profile and slightly wider. I much prefered the handling when I got back onto the Enkei's, and the ride was much better.

[busta]

Having played about with different wheel sizes and widths on a couple of small cars I've owned I have to say the biggest improvement in handling always comes from putting the original wheels and tyres back on.

Unless you are running a lot more power than standard or doing lots of track miles, then the only advantage of bigger/wider wheels is cosmetic. In which case, as long as they don't foul anything when you turn or the suspension compresses, they dont stick out of the arches and the circumference is within a few % of the originals ( check it out here ) then anything will do.

[wifiwupding]

im going to go for some 15" Speedline Turinis, i like the style of the originals but i think there just too thin, i know a bit about offsets but im not sure about changing the alloy width, do i just stick with the same offset as the original alloys and what would be the best tyre width for 6.5" alloys: 195mm or 205mm

195

195

any reason

[mrtwisty]

U lot dont no nuffink. You want some shiny 19's on it wiv lowest profiles u can get and cut 60mm off the springs. That'll make it handle wikkid innit! If you dont believe me buy Max Power. Oh, hang on...
