Tyre size change

[Subru]

Im going from a 205/50/R17 to a 225/45/R17 (because its cheaper), This means its wider and still similar rolling radius, will this effect handling at all with the added surface area?

Yep you should feel a difference in the steering (little more consistent) and of course you'll get more grip on the dry.

Depending on the tyres and the car, it can also bring more understeer or more oversteer. For example, on my 86 I had understeer with my winter tyres that I didn't have with my summer tyres.

Tyres are your only connection to the road, that's why they are the most important thing to upgrade if you want to go faster and they can also impact the handling

Sounds good.

Yep tyres are very important. Im getting new Bridgestone re003's on mine which is a lot for how slow the car is although Im modifying my car to handle really well rather than be quick and just the addition of wrx struts, sti springs and sti rear sway bar has made a huge difference by cutting out some annoying understeer and it feels more stiff and cornerie

I moved from a 205 to a 225 wide tyre, grip improvement was great. Only side effect was the increased tendency to grab ruts in the road.

Great

Btw, having a car that handle well and suits your style of driving is needed to be quick. That's why racing drivers work with the engineers to tune the car to their liking.

So you should also be quicker if you are more confident in the handling of the car

Yea that makes sense, Im keen to see how much it effects handling.

Im also getting a alignment coz I put the struts in and I didnt really think about the camber untill the old struts were already out so I had to guess the camber  fail, even with screwed alignment and bald tyres the handling is still decent lol, not in the wet tho .
