Tyres !

[Guest ctd]

Question? Tyres or alloys? In my opinion the stock 155/65/14 tyres look a little skinny on the C1's. So the next option is alloys with fatter tyres; dam expensive. What about different tyres on the stock steel rims?? I looked at my wife's C3's tyres, 175/65/14's and these look as if they would fit the C1. Can anyone tell me if these tyres will fit C1 rims safely, without effecting handling etc?

They'd fit the rims safely, but they would increase the circumference and make your speedo inaccurate. If you go up in width, it is a good idea to reduce the aspect ratio.

 

I have copied the following from the Aygo Toyota forum, it may be of interest:

 

What changes can I make to wheel sizes ?

The standard wheels are 14 inch and are supplied with 155/65/14 tyres.

 

You can change to 13, 15 or 16 inch wheels without modifying the bodywork.

 

If you want to keep the standard 14 inch wheels but have wider tyres you can fit 185/55/14, this change will mean that when your are travelling at an indicated 70 mph you will actually be moving at 70.25 mph. You can also fit 195/50/14 tyres and at an indicated 70 mph you will actually be moving at 69.18 mph.

 

When changing wheel and tyre sizes there are 7 considerations. 1. The wheel size. 2. The wheel width. 3. The ET (offset - how far the wheel will stick out from the body work). 4. PCD (pitch circle diameter) the size in mm of a circle drawn through the centre of you wheel bolts. 5. The number of studs (bolts). 6. Tyre size. 7. The impact the changes will have on your speedometer (indicated) readings vs actual speed.

 

For 15 inch wheels you will need to buy rim (wheel) size 15x6.5 ET 37 PCD 4/100. In order to maintain the accuracy of the speedometer with this increased size you will need to put 195/45/15 tyres on. This change will mean that when you are travelling at an indicated 70 mph you will actually be moving at 69.92 mph. Alternatively for 15 inch wheels you can fit 175/50/15 tyres however this choice is limited to just 2 tyre manufacturers as this size is not very common. This change will mean that when you are travelling at an indicated 70 mph you will actually be moving at 69.86 mph.

 

For 16 inch wheels you will need to buy rim (wheel) size 16x6.5 ET 37 PCD 4/100. In order to maintain the accuracy of the speedometer with this increased size you will need to put 195/40/16 tyres on. This change will mean that when you are travelling at an indicated 70 mph you will actually be moving at 70.67 mph.

 

The recommended tyre fitments are therefore 13" 155/70/13, 14" 155/65/14, 15" 195/45/15 and 16" 195/40/16.

 

All wheels are offset 35 – 45 and bore 54.1. Offset 37 is ideal.

Thank's for the information and valuable it is. Looks like the wheels and tyres at staying standard.

I quite like the skinny tyres, it's nice to have a car that doesn't tramline badly for a change and they help the fuel consumption.

 

It's the wheel trims I don't like, so I've been running the car without. My wife hates the black wheels, so to pacify her, I've just ordered a set of the Citroen alloys to use with the original tyres :)

 

The price on the website is £127 a wheel, but the local parts man managed to drop the price so I'm getting 4 for the price of 3 :D

If you want the car just to look like it has alloys, you can buy the 'alloy look' wheel trims of the Aygo.

 

Should be a far cheaper option.

Thanks to downsman and colin C1 again for your advice. I decided to take a look at the Aygo owners web site and found a solution to a problem with the rear wiper and its ineffectivness. Their solution was to change the existing blade with a 16inch rear blade from Halfords ( W22 16"-400mm, ata cost of £6.79) This was rapidly bought and fitted yesterday, what a difference. A much clearer view out the rear, especially as yesterday was another wet day in North Wales :) .

with a 16inch rear blade from Halfords ( W22 16"-400mm, ata cost of £6.79)

I assume that covers the one and a half inches at the top of the rear windscreen thats not normally swept, thus causing us all to duck to see better :blink:

 

I have a feeling I will be visiting halfords for a W22 this weekend ;)
