Blackcircles.ca is currently showing the $400 off voucher at the top of this page as the lead offer, which is best for shoppers who have a single expensive set of selected tires or wheels that qualify for the fixed $400 reduction. If your purchase is of selected items that match that voucher, it gives a straightforward $400 off at checkout.
Small tyre purchases under about $800, if your tyre spend is modest, the 15% offers on particular ranges can beat small fixed discounts only when the basket is large enough. For example, on a $800 order of MICHELIN X-Ice Snow tyres, the 15% code reduces the tyre cost by $120, taking the total to $680, so use the 15% MICHELIN X-Ice Snow code when you are buying those specific tyres. (On a $800 order: original $800, percent 15%, final $680, saving $120.)
Buying one selected high end item or a mixed cart of selected items where the $400 voucher applies, use the $400 off voucher at the top of this page. On a $1,600 order of qualifying tyres or wheels, the $400 off voucher takes $400 off, leaving $1,200, which is a bigger saving than the brand specific 20% or 15% codes unless those codes apply to the same items and produce a larger absolute reduction. (On a $1,600 order with the $400 voucher: original $1,600, fixed $400 off, final $1,200, saving $400.)
Buying a full set of 4 tyres and 4 rims, the 20% off set code is designed for that exact purchase. If your full set totals $2,000 for the 4 tyres and 4 rims, 20% off equals $400, matching the lead voucher; for totals above $2,000 the 20% code gives a larger saving. For example, on a $2,000 set: original $2,000, percent 20%, final $1,600, saving $400. Above $2,000, 20% beats the fixed $400.
Brand specific shoppers, if you are buying MICHELIN, BFGOODRICH, Bridgestone, Yokohama, Pirelli or other models listed with 10 to 15% codes, use the relevant brand code only when it applies to the exact tyres in your cart. Those percent codes are limited to selected products and cannot be combined with other offers, so they are best when you only need that model.
Shopping sale or low stock items, several 10% and 12% offers are marked available while stock lasts and are automatically applied for some lines; use them if your tyre model is included and no higher value offer covers the same items.
Which one to pick: calculate the total tyre and wheel cost first, then take whichever offer leaves the lower total. If your qualifying items are a 4 tyre and 4 rim set and the cart total is more than $2,000, the 20% set code will save more than the $400 voucher. If the cart total on qualifying selected items is less than $2,000, the $400 off voucher will usually save more. No offer lists combination rules beyond the statements that some codes cannot be combined, so do not assume stacking.
