Q How to jack up a low car?

I’VE just bought a Mazda MX-5 which I intend to use on a few track days in the future. I’m planning to take spare wheels and tyres with me, but my trolley jack doesn’t fit under the car. Do I need to buy a new jack?

AYOU could get away with running the car up on to pieces of wood or ramps that are specifically designed for low cars. However, for the same cost as the latter, you could easily get a more suitable jack. When we tested these, our winner was Wolf’s Black Jack (above), which is a lowentry design and costs less than £45.

Q Running out of run-flat tyres

MY BMW X3 has Michelin run-flat tyres, and it was off the road for four days after a puncture because none were in stock. Why does BMW fit them and why does Michelin have none in stock? Paul Hardy, E-mail

AWHILE firms like Michelin and other big makers aim to keep all sizes in stock, there’s a risk that niche, low-volume sizes and specifications may be out of stock in the UK. You could take it up with your BMW dealer, because you are unlikely to be its only customer that requires these tyres.

Q Clear view on anti-UV bulbs

I WANT to upgrade the H7 bulbs on my 2017 Citroen C4 Grand Picasso. The manual says that I need anti-UV bulbs. How do I know which are anti-UV as none says on the pack, and which of your recommended upgrade H7 bulbs qualify? Joe Brown, E-mail

AUV protection is included in the ECE Standard R37 so any bulb meeting this has anti-UV protection. This applies to the top four from our last test: the Philips RacingVision, the Ring Xenon130 and Xenon150, plus the Osram Night Breaker Laser Next Generation. It’s in the standard, so this may be why it’s not mentioned on packs.
