Tyres as Neil suggests are varied and can be an emotive topic, but ultimately it’s an individuals own circumstances and preference that tends to dictate the choice. I am in my own opinion am someone who saves for the best tyre as it’s the contact surface between car and road thereby always buy a premium branded tyre, such as Michelin PS4 or PS4S (depending on size) or perhaps a Goodyear Eagle F1 SuperSport would be at the higher end of a budget if needing 4 at once. Albeit the GY Eagle are cracking tyres and can be bought for sensible money at circa 90 per tyre. The Michelin’s are right at the top of budget at circa 140 per tyre but there are suitable cost alternatives from budget at 60-70 (Chinese branded) or if you run a slighter lower profile in say 18” and a 40 profile then the costs drop a wee bit more because it’s a more common sizing as opposed to the 45 on the RCZ. Black circles or Camskills online will offer tyres by size or registration for a good comparison on what’s available and with good pricing, or if you have or know someone with a Costco card then they offer Michelin’s and Goodyear brands with offers on usually such as 80-100 off 4 or 50 on two etc. The old adage is still true - get the best you afford
