I am posting this for the information of other GS300h owners who are considering changing their tyres. Please learn from my own stupidity. Do not purchase Goodyear Eagle F1 Asymmetric 2 in size 235/45!
When looking at reviews, I found near-universal praise for these tyres (in other sizes) for being quiet, comfortable and low rolling resistance. Despite the fact that I know full well that tyre reviews are second only to food reviews for being utterly pointless subjective tripe, I allowed myself to be persuaded away from spending the extra on Michelin CrossClimates which have been recommended by owners on here. That was foolish, and it is going to prove to be an expensive mistake.
These tyres are not quiet. They produce noticeably more cabin noise than the OEM Bridgestone ER33s, which I did not consider to be a quiet tyre in the first place. They are perhaps more 'comfortable' in that they make the car feel as if it's driving through treacle. However, the biggest problem is that the rolling resistance is absolutely, utterly, appallingly terrible. Unbelievably, it has actually made a noticeable impact on performance - significantly more throttle is now required in any given situation, and the distance I can get in milkfloat mode has been considerably reduced. As a result, fuel economy is now catastrophically bad. I'm not talking a slight reduction - I'm talking a minimum 10% worse and on some journeys up to 20%. Where I would have been touching an indicated 50mpg on these cold days, I am now struggling into the low 40s and occasionally dipping down into the 30s. If I needed more proof that those ridiculous EU economy ratings are anything other than fabricated bulls--t then this is it - these tyres have the same rating as the ER33s they replaced, and the associated mumbo jumbo claims a maximum difference of 7.5% between A and G!
I hoped they might just need scrubbing in, but there's been no improvement after a few hundred miles. I have tried whacking the pressures up to 2.7bar, but this has had little impact on economy. It just makes the ride unsettled. And yes, I've checked they were fitted the right way around!
Clearly, these tyres can't be universally awful. I've actually got the Asymmetric 3s (the updated version) on my wife's Auris HSD and they're absolutely fine. However, on a GS300h they are an unmitigated disaster if you have even a passing interest in fuel economy. I hope this information may save others from making the same mistake as I have made.
Had to get a replacement battery in a hurry today for my 2003 IS 300 Sportcross, so went on-line.
Eurocarparts website was easy to use and had a tasty discount offer. They had a choice of 2 so I selected the more expensive one with 70Ah, CCA 540A, rating and ordered it 'click and collect'. £67.40 inc vat and 3 year g'tee which I didn't think was bad.
Now I've got it home I can see it doesn't fit the battery tray properly. The base area is too big to fit deep in the tray so it sits quite high. Also, the new battery is 10mm taller than my knackered battery. As a result, the standard battery clamp won't fit (the rods aren't long enough) and the terminals are worryingly close to the closed bonnet.
Is this a common issue?
Is there a work around or will I have to return it to eurocarparts?
Is there a generally recommended/ easily available battery that fits?
Thanks in advance for your replies!
