Spare wheel size

[jay c]

Just wondering what size spare wheel and tyre people carry in the wheel well. I have never carried one but might be driving further afield in the summer and don’t want to be caught out. I currently run 5” with 145r 15 on the front and 6” with 205 70x15 at the back. I know it’s going to be a massive compromise between the 2 plus what can fit in the wheel well.

Hi jay

we got mainly 145s as spares tyres, on a 5.5 wide gasburner they are real pain to get into wheel well[getting it past washer bottle and brake reservoir ], with a real 4.5 fuch its not quite so bad, with your car having such nice paint I would think a porsche space saver with space saver tyre might be the way to go so as not to scratch car putting it in or out of wheel well if its purely as emergency option.

same here (porsche 5.5, 5x130 steely and 145)
i want to change to a 4.5 soon for ease of getting it in the well

Also a 145 here.
But on a steel 5,5 porsche wheel.
But indeed it does scratch the fuel tank a bit.

145 on a 5.5 Riviera, fits easily.
You just need a protection for the tank as the wheel is wider than the tire...

I was looking at group 4 who do their aluminium LMZ (Porsche steel copy) in a 5” with either a 145 or 155 tyre. Maybe lining the well with a soft sheet. Or getting Jo to make a special cover/bag to prevent scratches. I suppose another option is to carry puncture sealant but I don’t know how effective they are.

Steve do you have the stock washer bottle in place? and the 67 brake reservoir?

[Steve67]

Richie, yes I have the original washer bottle and the 67 dual circuit reservoir in the car.

... and 6” with 205 70x15 at the back.

Consideration should be given to your spider gears in the diff. With those extra tall truck tires, a small spare will make the side gears and spiders of your diff spin fast in the diff housing.
My rear tire is 215/60/15s on Fuchs, so a bit shorter than stock. When I went to fit a spare, I used a 155/80/15 and an original 4½ Fuchs since that fits easier in the spare tire slot than a 165. I was pleasantly surprised when I offered the spare up to the rear tire and saw they were exactly the same diameter!  This is very important since I have a ZF in the trans. The last thing you want with a LSD is two different rear tire diameters.
I think you should try to find the tallest tire that will fit in the spare slot.

If you can find a straight, rust free VW 4" wheel, take it and your P spare to a wheel shop and get them to weld the Porsche's center into the VW hoop. It won't scratch and will be lighter!
