Hi. It's 2 am, I'm just home after getting a puncture at 11.30pm three miles from home. I think a nail entered the tread and then came out again. The near side front tyre deflated fairly quickly. I couldn't see a hole on initial examination so I was optimistic that the electric pump and canister of sealant would do the job, but in fact it didn't work at all. The sealant gushed out through a 2mm diameter hole which was near the centre of the tread. I jacked the car up, engaged neutral, rotated the wheel so the hole was at the bottom and more sealant dripped through, waited ten minutes and then tried inflating it again but only succeeded in producing another gush of sealant. My year's Toyota rescue expired last week, so I called the RAC who did not send out a repair man but simply dispatched a recovery truck straight away to deliver the car and me home. Tomorrow I shall have to jack it up, remove the wheel and take it to a tyre fitter for a replacement tyre. When buying the car I had expressed my misgivings about not having a spare wheel, but the salesman reassured me that the sealant is excellent and works for 90% of punctures. The RAC lady says sealant is rubbish and it never works. The RAC is dismayed at the number of times it has to recover vehicles when previously a quick wheel change would have sufficed. In 38 years of driving this is the first time I've needed recovery (three breakdowns all fixed at the road side, and several flat tyres all changed by myself is my previous tally). Lesson learned. I need a spare wheel. Question: Is the well at the back of the boot space where the charger lead lives big enough to hold a small space saver? I notice it has a curved bottom and wonder if it is used for that purpose in countries where a spare is mandatory? If not where else would you store a spare? What size wheel is needed? Will my friendly Toyota dealer be able to get one? Thanks for any advice Pete
