The reason I choose a 14 inch tire for the spare, instead of the 15 inch, is as follows: That's 1 inch difference - don't even think about using the 185/65x14 as a spare. Actually I've just run the sizes through a tyre manufacturer's comparison calculator and come up with : 185/65x14 = 23.5 185/65x15 = 23.7 Did you remember that its 185/65x14 and not 185/60x14? The 0.2 inch difference is just about acceptable, but, and a very big but, the sidewall flex on the 185/65x14 will be so much more than the 185/60x15 as to throw the whole car way out of balance as to make it dangerous even at quite low speeds, never mind freeway speeds. (skinnies get away with this by having much stiffer sidewalls, and clever construction, when compared to "normal" tyres) Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

I don't think that applies to Vic's low power front wheel drive car. (btw at least one of the high performance awd cars has, by design, different sizes front and rear - makes carrying a spare a grade one PIA) Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

deflation in a compact spare will happen above 50mph. That is not the only issue with skimpies - at elevated speeds the tread wears so much faster, due to the choice of rubber compounds in the tread required to give them similar grip to the wider tyres. They don't deflate at high speeds, they loose their grip, tread and sidewalls start to flex badly and generally become "unsafe". On the one occasion I have used a skimpie in anger I had to drive for about 40 miles on it before I could get it changed, and the tread was almost worn out in that distance, I didn't exceed 50mph, I drove as smoothly as possible and didn't indulge in anything wild - I had a lot of miles to do in the following two weeks and didn't want to wrap the hire car around the scenery on day two of my holiday. In your case I would suggest that's its a long term storage issue, and not having been replaced after use - remember what I said about the tyres being designed for one use? - rather then having been used at excessive speed.

You're not the only one without a spare. - Last year when I got a new set of tyres for my car I could only get four and they are very different tread pattern and size to the "spare", which is now decorating my garage rather than being attached to the car. In the UK its not an offense (or MOT failure) not having a spare but it can be both if you have a spare that is not road legal (the "spare" was just OK), or of a different size or tread pattern to the road tyres. I know what you mean about having to go past a uni at the start of year, all those freshers milling around like lost lambs, some with parents fussing; then the "seasoned" students arriving with cars loaded with their possessions. One day I might go back to one of my alma mater and do something different again - it would be nice to have yet another higher level degree ;-) Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

BBC put together a really nice summary of the Cassini Mission. I agree, Carlos, it is rather good. When the BBC is not wringing it's hands over 'political correctness', 'diversity' and 'Brexit', it is very good at this sort of thing. Just yesterday, I was looking at a similar thing for Rosetta.

Now I have a conundrum, when I'm ready to buy a rim for the full size spare tire, which should I get? It's a spare, a $40 steel rim is all that's needed. No brainer. Grant Darwin NT |

Watch craigslist. When I sold my last jeep I had to sell my spare set of wheels. I had a set of road tires and a set of off road tires. I sold the offroad tires and wheels for $60. ![]() |

Over the years I've bought too many second hand rims that just weren't worth a dime, so I think you've done the right thing and "gone new", with the added bonus of being delivered to your door which means no worries about having to chase around to collect from some obscure corner of the countryside only to discover its not the wheel you thought it was...

Yes, Chris, the insurance companies drive me crazy with some of their attitudes.....when it suits them. For example, apart from the Legend, I have a Rover 216 Coupe (first registered to a very prestigious address in London - SW1A 1AA). Quite a nice little car; nippy, fairly good on fuel and being Honda-powered, reliable and they look great. The standard tyre size is 185/55/VR15. The car is apparently capable of 120 mph, yet, the tyres are rated to 150 mph, when an H rated tyre would've been perfectly adequate. I can guarantee that anyone who runs over a sheet of paper in one, at 70 mph, will end up with their spine parting company from the rest of their body and either striking a satellite, or it will go in the opposite direction, saving huge amounts of money in exploration costs for oil companies and geo-thermal start-ups! I've heard of some owners putting on '65s' with a reduced width, just to save their back. Yet, to appease the insurance companies, I have to use the V rated tyre, when I can't even imagine, what it would be like at even 80 mph - indeed, when an older one I had, hit a pot-hole at 25 mph, a mounting for the rear anti-roll bar was torn off. Of course, one can tell insurers about tyre changes that are non-standard, but you'd think a little 'common sense' and latitude would prevail. Don't take life too seriously, as you'll never come out of it alive! |

Car manufacturers are crazy when it comes to the speed rating for tyres. Take my current Discovery, the factory installed speed limiter is set to 115 mph, but LR say I must fit "V" speed rated tyres, which are rated for ~150mph. Granted the load rating of 111 is sensible on a vehicle that empty scales at 2.7tonnes. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

My old '72 Buick Electra with 455cid weighed about 4500lbs. Speedo went to 120.....and it would come to within a few mph of that, 4bbls wide open and roaring. A roaring cloud, with thunder under the hood. "Time is simply the mechanism that keeps everything from happening all at once." ![]() |

The '72 Electra has a hp/weight ratio of about .048 hp/lb. The '06 GT has a hp/weight ratio of about .089 hp/lb. Not to mention aerodynamics....LOL. So it goes to figure that the GT would have a much higher top end. What made those big old Buick boat anchors so much fun to drive was that the 455 had very strong stump pulling torque at the bottom end. Crack those 4bbls open and they would launch well enough to surprise some folks. "Time is simply the mechanism that keeps everything from happening all at once." ![]() |
