Funny handling with RE070s

[boon]

So I just went from MY01 225s on 17x7.5s to RE070s on 17x8's

I'm noticing (especially at low speed) that the steering is very... wayward? Twitchy? I'll be driving along a straight piece of road and it wants to twitch all over the place. Most commonly it wants to pull slightly to the left, but a fair amount of the time it's completely fine. Also fine at higher speeds (60kmh+?)

Is this the effect of a wider, much grippier tyre wanting to follow the road a lot more? Or is something funny going on here.

On a semi-related note, how often do you guys replace your PS fluid? I wonder if mines about due...

The stiffer sidewalls in the RE070 can cause this kinda tramlining effect. Common with this tyre (and semi slicks) and quite noticable when switching from normal road tyres.

my semis do that a bit

They grip like jebus but I'm not sure I'm in love with them... especially with the price, noise and twitchyness... but the grip is pretty phenomonal, coming from MY01s.

I kinda suspect they won't pass their next WoF in which case I think they'll be relegated to track-day tyres, one day maybe haha.

What would you guys recommend in a 17x8? RE001? RE11? P-Zero, T1R... the list goes on...

Yep i got this too when going to them.

All is forgiven when you drive them hard on a twisty bit of road....

I get that with 225 semis. You could try a narrower tyre, if your car is an older one.

Yeah, I got quite a bit more tramlining with RE070s. It's normal for that sort of tire. They're also pricey, really noisy, and wear quickly. But dry grip, turn-in and steering feel are just soooo much better.

yeah its kinda scarey sometime driving semi's on the road, i get those all the time
